I have similar problems with my samba setup. I have a 100BaseT network, and can get consistent 5000kb/sec through FTP (I assume this is a disk limitation). Any transactions that use samba are significantly slower, usually 5x to 10x slower. So obviously this is a samba tuning issue. I'll be darned if I can find anything that helps me though. I have checked out the 2 performance text files in /usr/local/share/docs/samba/ to no avail. (yes I have DMA mode turned on) So if there is a solution to this, I'd be interested to hear it to. -Chris To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
