I have more than 20 active cpu

Hi,

I have more than 20 active cpu (24), so why limiting the number of threads to 20 ?

Thanks.

Threading creates overhead, I'm sure this could be solved if it's still an issue for you. However, multithreading something that reads from disk doesn't always have any benefits, even when you run drives in RAID0, one of your CPU threads can easily chew trough the data in the speed that your disks are able to feed. And when using more than one threads often end with slower creation time because of overhead.

Only benefit I've seen from multithreading here is when my files are cached in memory, it's slower at my SSD, dual disk RAID0, and 10x Disk RAID 6.

If there are no real use cases for supporting more than 20 threads, this issue should probably be closed.
