Hello,while doing some ZFS tests with RELENG_8 I recognized a mysterious performace drop after an hour uptime. Now my first idea is to compare MSS and windows sizes before and after the performance drop.
How do I best capture them? tdpcump? It's GbE linkspeed...Or is netstat capable to show these values? Or is there any way to read out the values stored in tcp.hostcache?
Thanks, -Harry
