I have a small VPS with 64MB RAM. I use it as an internal proxy. I only have one index.php on this server, which has the logic to fetch data from another server using php curl and display to the client (this is done for every request - there are no local files whatsoever).
I have installed PHP APC so that the index.php lies in the RAM. Are there any disadvantages to having APC on a 64MB box? I have heard there can be fragmentation/swapping problems - but I assume not in my case, right? On a related note: Does CURL cache any data (enough to create problem with APC on a 64 MB RAM?).
Any tips on best practices on this box to prevent swapping/fragmentation would be very helpful (I am pretty much a noob with this).
thanks
