Hello, I am a bit surprised that my sql server does not use full 16gb of ram with 3 very active database of 6gb each.... When the server/service is restarted, it takes a good day or so for sql to grab all the memory available. I would expect SQL Server to load up all indexes and such into memory and keep them there and I believe almost all indexes are touch within a few min of service starting Is this something I should be concerned with? PS - my server is showing signs of stress btw and IO seems to be the bottleneck. I considered getting more RAM hopeing that sql server would be able to keep most of the database in memory so I am trying to determine why it is taking so long for it to use all 16gb right now. MANY THANKS for your help everyone!
