Hello, all, I'm working on some performance tuning using Linux servers with AFS clients and ftp server software to shuttle data from users on the net to my AFS file servers. While working on tuning things for performance and stability, the number one issue I run into is that if things get "too busy," all the processes go into a holding pattern where ps axo wchan shows them all in afs_cv_wait. [snip] Any tips/pointers? I'm ok with just capping the usage and declaring the limit to be somewhere below the threshold where things go horribly wrong. But if there is a way to get performance to degrade gracefully under a high load, that would be preferred. And if I forgot to post some important vital and super obvious piece of information... apologies in advance. ;-)
What parameters are you using for the client? What's rxdebug <client> - port 7001 -rxstats show?
