What value does everyone use here? I set it to 2M, not sure how to calculate the optimal value.
1M should be good for a media/CDN server.
What about a dynamic site, such as a forum?
AIO has no effect on dynamic site.
Hmm, there are static files on a forum though. Apparently, it does help when the iowait on server is high (backing up files), the forum will load whereas it'll stall if AIO is disabled.
AIO block size would be best the avg file size/raid stripe size.
I'd keep it low for a dynamic forum, 512 tops.
Enable MMAP/whatever the other file cache is (Not LSCache) the static memory file caches, set the memory higher, on the MMAP or whatever the 2nd is that doesnt say for uber small files, raise to maybe 2048 mB so that all JS/CSS are cached in memory.
If backing up if killing your IO make sure to run it at least busy times and maybe look into less resource intensive IO backing up.
