how often does a special socket block and go again ?
For monitoring throughput there are tools such as IPAudit that will monitor throughput. I can’t remember which tool I used to use for this purpose, but a quick search found IPAudit. I haven’t tried it, so let me know if it works, or if you know some better tools. You can use netstat -a under solaris and look at the Swind and Rwind columns for send and recieve window sizes. I’m not aware of any tools for monitoring how often a socket blocks. Someone please add a comment if you have any suggestions for this. You could parse the output of snoop/tcpdump to get some of this information. Let me know if you know a good parser and I’ll list it here.
