Then git bisect could be used to find the one kernel commit that

Hi all,
just ran a very silly test, all with openvpn 2.1.1, on my laptop running
FC12 (2.6.31.12-174.2.22.fc12.x86_64) , Intel(R) Core(TM)2 Duo CPU
T9300 @ 2.50GHz, connected to a 100 Mbps LAN
server side:
openvpn --ifconfig 10.222.0.1 10.222.0.2 --dev tun --secret secret.key
--cipher no

Could some kind of crypto acceleration of OpenSSL be in play?

I believe this has been discussed before, but I noticed recently that a
Linux-based OpenVPN client (Linux 2.6.24, OpenVPN 2.1.1) spends a lot
more CPU time in kernel space than in user space. This is surprising,
given the fact that all of the CPU-intensive cryptographic operations
are being do
