Maybe you want to look at your memory and swap usage and
/proc/sys/vm/swappiness.
If the other app was swapped out for no good reason, but you have enough
ram you could disable swap altogether or reduce swappiness to a low
value.

That shouldn't be needed if you have enough ram.
If memory size is an issue maybe you could try ramzswap:
