Also take a look at the CPU usage. Is it reaching 100% when problems start? Increase the number of processes, e.g children=10 and see if the performance increases. Like Henning said start finding the bottleneck. Disable all external components like DNS lookups and DB queries (usrloc, authentication, accounting). Then take a look if the performance is better. Then add again one after the other and find the bottleneck. regards klaus _______________________________________________ Users mailing list Users@lists.openser.org http://lists.openser.org/cgi-bin/mailman/listinfo/users
