MBP getting slow?

Question

Ok so my computer is about 5 or 6 months old now. Its a mbp intel core duo with 512mb of ram. It has been running like a charm. It is so fast for only 512mb of ram I must say, but lately things I would normally do take allot longer.
For example: Sometimes iTunes can take up to 6 bounces to open. Normally I could do it in two to 3. Mail can take up to 5 bounces. It doesn't do it every day though. Its odd it seems to have its bad days. Some days it is nice and speedy again So what the heck is going on? Is there an app I can get to test the speed of my ram or anything?

Answer 1

Here I did the test. I have no Idea how to read this. can somebody read it and tell me what my system is lacking? Thanks. --By the way I noticed initial boot times are getting slower aswell.
