(being a userland IKE daemon) but on the performance of<br>
the hardware platform, the number of cores available and<br>
preferably a recent Linux version which is able to make<br>
full use of multiple cores. The LinuxTag 2010 paper by<br>
Steffen Klassert gives some benchmark figures:<br>

Hi<div class="im"><br>
Thanks for your quick reply<br>
For example, in our test lab,we want to generate 1G traffic between 2<br>
node.If I conduct this traffic on "ipsec" tunnel, how amount of<br>
performance will be decreased? maybe 200MG or more.<br>
anyhow, encapsulation of packets has some overhead on performance.<br>
<br>
Thanks in advance<br>

Hello Nima,<br>
<br>
what do you understand by bandwidth?<br>
<br>
- The ESP throughput of encrypted payload packets?<br>
<br>
- The IKE throughput of negotiated connections?<br>
<br>
Regards<br>
<br>

Hi<br>
Before anything,thanks to anyone that contributes to this project.<br>
How bandwidth can StrongSwan handle?in fact I want to know maximum<br>
bandwidth that strongswan can handle.<br>
<br>
Thanks in advance<br>
