Hi Guys


I own a 13 inch Macbook Pro 2.3 GHz Intel Core i5 which currently has 4GB of memory. It often seems to run quite slowly, so I was wondering whether it might be worth upgrading the memory on it. Based on what I've read online, it seems the way to tell if you could benefit from more memory is to look at page ins/outs. Compared to what I've seen online mine seem to be quite high.


I wondered if you guys could advise as to whether or not I could benefit from some additional memory? Would I actual notice any improvement in the performance of my MBP If I were to add more?


Thanks in advance!

    General rule is if page outs exceed 10% to 15% of page ins, you can use more memory for the programs you run. In the picture you posted, essentially page outs = page ins. You can use more memory.


    Your 2011 MBP can use up to 16GB of memory. Recommend installing in matched pairs, ie 2 x 4GB, for slightly better performance. OWC and Crucial are two good sources.

    The page in/out values accumulate and are reset when you reboot. So, while you may not have been running much of anything at that moment, it's reflecting events since your last boot.
