[ic] Interchange slows down over time

Hi Mike,

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.

Kind regards,
