Still takes more time to show directory listing (ls -la) compared to scheduler and the listing itself is a bit "jumpy". Scrolls about 20 lines, then waits for a moment, then scrolls forward again and so on. The stopping moments are actually very short, but noticeable. This is while the seti's are running, 2CPU PIII-500. -- Vallo Kallaste To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
