I wonder if you documented [or made a "bullet-point" list of] the major issues ? What were the settings that you had to change / reconfigure ? At 10:24 PM Thursday, you wrote: We use a lot of the Net filer/ here Dennis. We bumped to fibre cards and many various option to speed things up. We get awesome performance...BUT... And a big butt. We have had the system slow down vastly when certain settings were not set correctly like async stuff. We had a router set wrongly so that our disaster recovery site lines were slow and cause some special file to fill up and slow the system down. We also have the continous access disaster recovery software...with certain settings not set (async something) also create big impact to the entire system. Let me tell you.. Real fun tuning when you have SQUAT for monitoring tools. This net filer stuff works well when all the kinks are worked out..and we are running it with quite a load. Network connection issues were cause of I would say 3-4 major issues..(during setup of 2 year project).
