I uses RAR since it was released a decade ago perhaps. However it is good for desktop applications I just found that on server where I need to compress a lot of text files every weekend it takes ages.
I looked into CPU usage and RAR takes around 15% of total CPU time. Nothing else is running alongside.
I have Xeon 8 threads (4 HT cores) and Windows 2008 R2.
Is there a compression software which zips no worse than RAR with option Best and takes advantage of all cores and HT ?
P.S. Also has to have x64 version
