We have started using an accounting product which runs on SQL express 2008. It is installed direct to a PC with the database also stored on the same PC. The package is a little sluggish . The PC is a core i3 with 8Gb RAM Win10 Pro 64bit.
With the package open and running the SQL server instance is the highest use item of memory according to task manager at around 180 meg . Total memory usage all processes is around 29-30%.
As SQL express 2008 instances cannot be allocated more than 1Gb RAM is there any value in increasing RAM to 16GB ?
