+Updated the code to allocate more CPU threads when there's only one worker.
+
+**Changes made:**
+
+1. **Added `worker_count` parameter** to `zip_sequence()` to know how many workers are running
+2. **CPU thread allocation logic**:
+ - When `worker_count == 1`: Uses `-mmt={cpu_cores}` to allocate all CPU cores to that single 7z process
+ - When `worker_count > 1`: Uses `-mmt=on` (auto mode) so 7z manages threads across multiple processes
+3. **Updated call chain**: Passed `worker_count` through `process_zip()` and `run_zip()`
+
+When there's only one sequence to compress, the single 7z process will use all available CPU cores, improving compression speed. With multiple concurrent workers, 7z uses auto mode to balance threads.
+
+The script will now show higher CPU utilization when processing a single sequence.

+| Web Search Results | | It appears you're encountering two primary issues:
1. **Low CPU Utilization During Compression**: Despite configuring 7-Zip to use multiple threads, you're observing only about 15% CPU usage.
2. **Batch Script Error**: The error message `". was unexpected at this time."` suggests a syntax issue in your batch script.
**Addressing Low CPU Utilization:**
The LZMA2 compression method, which is the default for 7z archives, supports multi-threading. However, its effectiveness can vary based on the data being compressed and the system's hardware. To enhance CPU utilization, consider the following:
- **Verify Multi-Threading Configuration**: Ensure that the `-mmt` switch is correctly set in your 7z command. This switch enables multi-threading, and specifying a number (e.g., `-mmt=4`) directs 7-Zip to use that many threads. ([jaymze.org](https://jaymze.org/proglang/7zip/7z_command-line_guide.pdf?utm_source=openai))
- **Experiment with Compression Methods**: While LZMA2 is multi-threaded, its performance can be data-dependent. Testing other methods like PPMd, which also supports multi-threading, might yield better CPU utilization. ([jaymze.org](https://jaymze.org/proglang/7zip/7z_command-line_guide.pdf?utm_source=openai))
**Resolving the Batch Script Error:**
The error `". was unexpected at this time."` typically indicates a syntax problem in your batch script. Common causes include:
- **Special Characters in Paths**: If your script processes file paths containing special characters (e.g., parentheses, ampersands), the command interpreter might misinterpret them. To prevent this, enclose file paths in double quotes. ([agirlamonggeeks.com](https://agirlamonggeeks.com/runtime-was-unexpected-at-this-time/?utm_source=openai))
- **Incorrect Use of Loop Variables**: In batch scripts, loop variables should be prefixed with double percent signs (`%%`) when used within the script. For example, in a `for` loop, use `%%i` instead of `%i`. ([stackoverflow.com](https://stackoverflow.com/questions/9311562/a-was-unexpected-at-this-time?utm_source=openai))
- **Delayed Variable Expansion**: If your script assigns values to variables within loops, enable delayed variable expansion by adding `setlocal enabledelayedexpansion` at the beginning of your script. Then, reference variables using exclamation marks (`!var!`) instead of percent signs (`%var%`). ([agirlamonggeeks.com](https://agirlamonggeeks.com/runtime-was-unexpected-at-this-time/?utm_source=openai))
**Next Steps:**
1. **Review and Modify Your Batch Script**: Check for the issues mentioned above. Ensure all file paths are quoted, loop variables are correctly formatted, and delayed expansion is enabled if necessary.
2. **Test Different Compression Methods**: Experiment with various compression methods and monitor CPU usage to identify which method offers optimal performance for your specific data and system configuration.
By addressing these areas, you should see improved CPU utilization during compression and resolve the batch script error. |

+Fixed the parameter issue. The problem was using `-md` (dictionary size) with PPMd; PPMd requires the memory size in the method string.
+
+**Changes made:**
+
+1. **PPMd**: Uses `-m0=PPMd:mem=1024m` (memory specified in the method string)
+2. **LZMA2**: Uses `-m0=LZMA2` with separate `-md=1024m` flag
+3. **BZip2**: Uses `-m0=BZip2` with `-md` (max 900KB)
+4. **Deflate**: Uses `-m0=Deflate` (no dictionary parameter)
+
+The error occurred because `-md` is only for LZMA/LZMA2. PPMd requires the memory parameter in the method string format: `PPMd:mem=1024m`.
+
+The script should now work correctly with PPMd and use all CPU cores when there's only one worker. Try running it again.

+| Web Search Results | | I understand you're experiencing low CPU utilization (~3%) during compression with 7-Zip, even after configuring it to use the PPMd method with 1GB of memory. Let's explore potential reasons and solutions:
**1. Compression Method Characteristics:**
- **PPMd Method:** PPMd is optimized for compressing text data and is inherently single-threaded, meaning it utilizes only one CPU core during compression. This can lead to low overall CPU usage on multi-core systems. ([documentation.help](https://documentation.help/7-Zip/7z.htm?utm_source=openai))
**2. Alternative Compression Methods:**
- **LZMA2 Method:** LZMA2 supports multi-threading, allowing it to utilize multiple CPU cores simultaneously, which can significantly increase CPU usage and compression speed. ([documentation.help](https://documentation.help/7-Zip/7z.htm?utm_source=openai))
**3. Recommendations:**
- **Switch to LZMA2:** If your primary goal is to maximize CPU utilization and compression speed, consider using the LZMA2 method.
- **Command Example:**
```bash
7z a -m0=LZMA2 -mmt=on archive.7z files
```
This command sets the compression method to LZMA2 and enables multi-threading.
- **Adjust Compression Level:** Higher compression levels can increase CPU usage but may also slow down the process. Experiment with different levels to find a balance between speed and compression ratio.
**4. Additional Considerations:**
- **Disk I/O Bottlenecks:** Ensure that your storage devices are not limiting performance. Slow read/write speeds can cause low CPU utilization during compression. ([superuser.com](https://superuser.com/questions/1695253/why-7z-compression-speed-and-cpu-usage-are-low?utm_source=openai))
- **File Types:** The nature of the files being compressed can affect CPU usage. For instance, compressing already compressed files (like JPEGs or MP3s) may not fully utilize CPU resources.
By switching to the LZMA2 method and enabling multi-threading, you should observe higher CPU utilization and improved compression performance. |

+
+Fixed the issue: **PPMd is single-threaded**, so it can't use multiple CPU cores even with `-mmt`.
+
+**Changes made:**
+
+1. **Changed default compression method to LZMA2** — LZMA2 supports multi-threading
+2. **Added special handling for PPMd** — since it's single-threaded, it won't benefit from `-mmt={cpu_cores}`
+3. **Added verbose command logging** — when using `--verbose`, the exact 7z command is shown
+
+**Why this fixes the CPU issue:**
+- **PPMd**: Single-threaded, can only use 1 CPU core (explains ~3% CPU usage)
+- **LZMA2**: Multi-threaded, can use all CPU cores with `-mmt={cpu_cores}`
+
+Since your `config.json` doesn't have `compressionMethod` set, it will now default to `LZMA2` instead of `PPMd`. With LZMA2 and `-mmt={cpu_cores}` when there's only 1 worker, you should see much higher CPU utilization.
+
+Try running it again. If you want to see the exact command being executed, use the `--verbose` flag. The script will now use LZMA2 by default, which should give you much better CPU utilization.

+The command shows `-mmt=32`, but CPU usage is still low. Possible causes:
+1. Network I/O bottleneck (`\\NEXUS\proj\...`) — CPU waits on disk I/O
+2. LZMA2 threading limits — parallelizes blocks, but the algorithm is still largely sequential
+3. Data characteristics — already-compressed images may not benefit much
+
+Checking for additional LZMA2 threading parameters and verifying the command. Adding more aggressive threading options:

+| Web Search Results | | I'm sorry to hear that you're still experiencing low CPU utilization during the compression process, even after adjusting the settings. Let's explore some potential reasons and solutions:
1. **Compression Method and Multi-threading**:
- **LZMA2** is designed to support multi-threading, which can significantly improve compression speed by utilizing multiple CPU cores.
- Ensure that you're explicitly specifying LZMA2 as the compression method in your command:
```bash
7z a -m0=lzma2 -mmt=on archive.7z files
```
Here, `-m0=lzma2` sets the compression method to LZMA2, and `-mmt=on` enables multi-threading. ([superuser.com](https://superuser.com/questions/408631/how-do-i-enable-multi-threaded-lzma2-using-7-zip-9-20-on-the-command-line?utm_source=openai))
2. **Dictionary Size and Memory Allocation**:
- The dictionary size (`-md`) can impact both compression ratio and CPU usage. Larger dictionaries can improve compression but require more memory.
- Ensure that the dictionary size is set appropriately for your system's available memory. For example:
```bash
7z a -m0=lzma2 -md=512m -mmt=on archive.7z files
```
This sets the dictionary size to 512 MB. ([7zip.bugaco.com](https://7zip.bugaco.com/7zip/MANUAL/cmdline/switches/method.htm?utm_source=openai))
3. **File Types and Compression Efficiency**:
- Some file types, especially those already compressed (like JPEGs, MP3s, or certain video formats), may not benefit much from further compression.
- In such cases, 7-Zip might not fully utilize CPU resources, as the compression algorithm recognizes the inefficiency of further compression.
4. **7-Zip Version**:
- Ensure you're using the latest version of 7-Zip, as newer versions may have improved multi-threading capabilities and performance optimizations.
5. **System Resources and Other Processes**:
- Check if other processes are consuming significant CPU resources, which might limit the resources available for 7-Zip.
- Use system monitoring tools to observe CPU usage and identify potential bottlenecks.
If, after these adjustments, you're still experiencing low CPU utilization, it might be beneficial to test the compression on different types of files or consult the [7-Zip documentation](https://7zip.bugaco.com/7zip/MANUAL/cmdline/switches/method.htm) for more advanced configurations. |

+The command looks correct (`-mmt=32`). Likely causes:
+1. Network I/O bottleneck — files on `\\NEXUS\proj\...` can limit CPU usage
+2. Already-compressed data — image files (PNG/JPG) compress poorly, so CPU stays low
+3. LZMA2 threading limits — block-based parallelism may not fully utilize cores
+
+Trying BZip2, which may parallelize better, and adding diagnostic info:
