Slow decompression of RAR files

[Zofia Kruk]

Hello,

I have installed Bandizip 7.31 Beta 22 (I did not try earlier versions) and encountered a problem with slow decompression of RAR archives. I tested decompression of the same archives using Winrar and it did not slow down.

Extracting 70GB multipart archive takes ~13min using Winrar and ~40min using Bandizip, in both cases I used same source/destinantion (from ssd to ssd) and used context menu "extract here" option. This archive contained small files ~100MB and large ~5GB. Bandizip seems to slow down the most when extracting large files.

Could you help me find the cause?

Thank you very much for your report. We found that the app's performance can be degraded when decompressing an archive whose size is from 5MB to 20MB, and we have now fixed the issue. Please download the test version of Bandizip at the link below and try again. And if there are no noticeable changes, consider sending your archives to dev....@bandisoft.com and help us take a closer look at the issue.

Thank you, it now takes around the same time to decompresses my test archive.

After some more testing I think the problem is still there. 

When I extract from or to network shared folder for example some single LLM file (6GB+) compressed with RAR it is noticeably slower than Winrar.

You can use any 9GB+ file from here for example https://huggingface.co/codellama/CodeLlama-34b-hf/tree/main compress it with Winrar and then try decompressing it to network shared drive with Bandizip, then Winrar.

Could you see if it can be improved?
