I don't have any problems with tcpdump and CPU load as long as the client count stays relatively low. But when I get those 60k+ active client peaks the system does get loaded down. I don't generate load statistics, but on a couple occasions I've been logged into the system during a huge peak and the load average was in the 2.25-2.5 range. For comparison, a typical active client count for my ntp server is in the 5000-5500 range, and ntp_clients and tcpdump show 0.0 %CPU most of the time with a 0.00 load average. Since this new DNS system has been unveiled for the pool, hopefully those large peaks are a thing of the past. -- Dennis Hilberg, Jr. <[EMAIL PROTECTED]> NTP Server Information: http://saturn.dennishilberg.com/ntp.php _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
