Check out the TSM performance and tuning guide. It has specific recommendations for all of those types of values. TCPWindowsize should be set to 63 on Linux.

Should I set it to 2048 in my dsmserv.opt or leave it as is? Thanks, Geert PS: Basically, we were looking to find an answer to the intermittent disk writes, I would expect a streaming write instead of intermittent writes to disk.
