I understand SQL 2005 64-bit uses all available RAM by default, but I migrated our SQL server to new hardware over the weekend by doing a fresh install and now the production database (which is 32gb and being used by 5+ people right now) is using about 2.3gb of RAM on a server that has 32gb of RAM.
The older server, which was running the same Server 2008 64-bit OS, always showed SQL using most available RAM, but I assume someone must have made a change to memory properties on that server.
Clearly by default it isn't using all available RAM so is that OK or should I tweak the server memory settings?
