It might be something pretty basic. I just had it in a similar
constellation with a database server. Did you test whether your network
interface supports more than the maximum throughput your graph is
showing? I realized that GBit interfaces are sometimes already maxed out
at 300-400 MBit and when I added additional interfaces and created a
bonding interface the load went away and everything was working fine again.

Just a thought.
