Hi, this whole io-threads business makes me nuts. In my tests with webservers serving many small images, I could never see remarkable difference when playing with io-threads, neither on server nor on client side. besides that, it still confuses me how to know which settings are recommended. in on posting is said, io-threads on the client may help: http://lists.nongnu.org/archive/html/gluster-devel/2007-11/msg00192.html in some other postings, it's said it doesn't have an effect on client-side, i.e.: http://lists.nongnu.org/archive/html/gluster-devel/2008-01/msg00241.html and it still remains unclear (at least to me) how many threads should be configured. if I understand that each thread handles one request parallel to the others, than if I have 1000 parallel request, wouldn't I want to set io-threads to a similar high number? say I have 3 webservers, each handling 100 requests in parallel, all using the same glusterfs mount. should it improve performance if I - set io-threads to 100 on each client - set io-threads to 300 on the server ??? Thanks once again, Sascha
