By default, memcached is listening on port 11211 for all connections. But for a single server, it’s better to config memcached to use unix socket which improve the performance and reduce the legacy. On freebsd, it’s easy to change from TCP/IP to unix socket. But there are some steps you need to pay more attention. M 2048 -s /tmp/memcached.sock".

System Administrator's Blog. Windows, VMware, Citrix, FreeBSD and Web servers. FreeBSD: use mrsas driver to replace mfi driver. My server got a Dell PERC H330 raid card, and I made it’s working in HBA mode to make sure that it can get best performance under FreeBSD with zfs. But every time when I boot the server, I’ll get below error message and it take a long time to pass the disk check stage. After research, it seems this timeout error was caused by the old mfi driver. This entry was posted in FreeBSD.
