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..

My doubt is:
If cpu overhead is directly proportional to ipsec client amount transfering bulk data, why my test delivered other result?...
1 IPsec client----->cpu=61%
2 IPsec client----->cpu=85%
3 IPsec client----->cpu=91%
4 IPsec client----->cpu=93%
5 IPsec client----->cpu=92%
6 IPsec client----->cpu=88%
7 IPsec client----->cpu=83%
8 IPsec client----->cpu=81%
the test was realized two times and similar results
I am wrong???
Thank!

it is not neccessairly going to be linear since there are other things going in the background...what class of machine is this(cpu/ram..etc)?

what do things look like when ipsec is off? does the cpu usage drop a whole bunch or does it hover in the 60-90% range? i am assuming you are using it for firewalling? how about e-amil filtering/forwarding/anti-virus..etc??

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?
