Thank you very much for the reply. Actually there is plenty of memory
total used free shared buffers cached
Mem: 24677748 16096552 8581196 0 140748 9174228
-/+ buffers/cache: 6781576 17896172
Swap: 20578296 203172 20375124
And increase in response time is about 3-4 seconds and then it stays
this way. Just after the restart the reponse time is below 1 second and
after some 15-20 minutes starts increasing. It seems that the same issue
does not occur when setting traffic mode to "high". But with "high"
mode we had the problem that occasionally interchange failed to send
some emails and encrypt credit card details.
