On my activity monitor i was just looking at my Ram usage, which is fine, but then i saw the VM size and it was HUGE! Does this effect how fast my mac will run ?

Can you empty it, like you would empty a cache?

Also, whilst im here, can someone simply explain page ins and page outs please?

Thanks

The short answer is no. VM size is just the total amount of RAM allocated to POSSIBLE use by all the running processes. Sort of like how you have a $10,000 credit limit on your credit card, but your actual liquid cash on hand is way less.

Bottom line: ignore VM size. Swap used and page-outs are the important measures to notice, and yours are in great shape.
