Hello All: I've been requested to add some TCP tuning parameters to some CentOS 5.4 systems. These tunings are for the TCP receive buffer windows: net.core.rmem_max net.core.wmem_max Information on this tuning is broadly available: http://fasterdata.es.net/TCP-tuning/linux.html http://www.speedguide.net/read_articles.php?id=121 Potential downsides are available: http://www.29west.com/docs/THPM/udp-buffer-sizing.html >From the above, the rmem size is a function of the number of listening processes times the size of the receive buffer. Apache can initially create a bunch of server processe...

I tried almost every samba tuning tip I could find to no avail. The only optimisation left to smb.conf at the moment is debug level = 0. As one can see the robocopy throughput is merely half of what

Hi, We're having performance problems with SolidWorks on our shares. Copying the entire entire solidworks project to local disk and opening from there takes around 30s, but opening from the share directly takes minutes. Apparently solidworks knowledge base has this to say about Samba: > The official policy with regards to Linux Samba is that our legal department has advised us that the
