<snip/> Just to reinforce Vernon and Jo's points, we have DNS servers running Linux at ARIN pushing 25~30k packets per second. Overall CPU utilization (across all cores) is under 10%. Interrupt rates tend to be around 15~18k per second. cheers, Matt _______________________________________________ dns-operations mailing list [email protected] https://lists.dns-oarc.net/mailman/listinfo/dns-operations dns-jobs mailing list https://lists.dns-oarc.net/mailman/listinfo/dns-jobs
