4 percent? is that the amount of hte increase or the total usage? if it is the total usage i would not worry..if that is the percentage increase as long as your cpu does not hang around over 60 or so percent i would not worry about it either..

No service running, no firewalling neither smtp proxy, neither NAT,neither antivirus,etc.
The network is isolate, to prevent virus,broadcast,etc.
When IPSec no work (VPN enables but no work) the CPU usage is lower 2%

you are running freeswan on the Astaro box? if nothing esle is running then either you ahve a hardware problem or something is chewing up your cpu cycles..go into webmin..under reporting click hardware..scroll down to the process list and copy and paste the list here..[:)]

You are not understand my question:
My system does not have surcharge of CPU, destiny that CPU's utilization low to measure that connect but clients IPSec (this is rare or not?)

PS: Freeswan is the implementation incorpored to ASTARO you were not tasting it?

I am no problem..but astaro behaviour is rare in the ipsec vpn roadwarrior test (please see the 4th post)
I try connecting 1 for 1 ipsec client. Since 1 to 4th client cpu is increase, spending up to 90%......But since 6 to upper decrease to 80% strangely. This is normal??

Thank

aha..ok...i think i understand...the cpu decreases when you add more than 4 ipsec clients..that one i do not have an answer for..however linux is a different animal it may decrease to the the hernel or module readjusting hte load(this is jsut a wild guess here as i do not claim to understand Linux memory workings/caching in this instance)
