I just updated from 15.0 to 15.5 inplace upgrade and everything went fine. System response time is good. This is on a windows 2003 server.

I also did the following on my site about 6 months ago to solve very slow web interfacing.

Added the DBRINDEX=0 switch to site.cfg per

I also needed to break some of the large indexes up into smaller cycles from monthly to weekly.

One thing that slowed my lists down recently was someone sending an email with a 10 meg attachment to about 300 people. I had to add a sizelim to the list.

Since you have a new server are the permissions and configurations the same?

Subject: Listserv slowness after upgrade

We just updated our Listserv from 14.4 to 15.5. At the same time moving 
it from a SUN 280R running Solaris 8 to SUN 280R running Solaris 10. The 
upgrade was successful when we tested it with a limited number of lists 
(about a dozen). Then we moved the entire system over with 1,300 lists. 
The system works but seems to run very slowly. With only three site 
managers signed in and running tests, the web interface was slow to 
respond and the subscriber's page would timeout while reloading. We 
think that everything is functioning properly but find the slowness 
unacceptable. We're hoping this is just a configuration issue and that 
some tweaking and fine tuning will relieve the slowness.

Does anyone have any insight into where we should look?

thanks,
Mike
