Description

We have two server connected next to each other. When we're iperfing each other through 'simple' physical interaces - we're getting ~5GB/S of bandwidth. But when im sending traffic through tunneled (strongswan) GRE interface. Im getting only ~400mbits of traffic and some ksoftirq process is utilized. Is there are some remedies ? Server is quite powerfull: Intel Xeon E5-2620 0 @ 2.00GHz
