Dreamhost ps sql considerations

I’m trying to determine if getting a DH PS sql server will help with sluggish sql response times. I’d like to see what kind of memory usage I have now on my shared sql server. Is there any way to see this without moving it to a PS? I guess I could move it within the first week and test it out, but I don’t want to have to ask to move it back. I’d like the graphs showing usage for my shared sql server.
