My second thought is that if there truly is an issue, it's in the network tuning on the Windows systems, not on your Linux systems. Since your Linux systems' response times are on the order of 1/3 the time of the response times for the Windows systems, so it doesn't appear that your Linux systems are the issue. -- Mike Burger http://www.bubbanfriends.org Visit the Dog Pound II BBS telnet://dogpound2.citadel.org or http://dogpound2.citadel.org To be notified of updates to the web site, visit: https://www.bubbanfriends.org/mailman/listinfo/site-update or send a blank email message to: site-update-subscribe@xxxxxxxxxxxxxxxxx -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
