The only long-term solution is to use a different method such as VMX over SSH. vCenter is just fundamentally bad.

But i think i've to blame vcenter cpu which is stuck at 100%.

But i think i've to blame vcenter cpu which is stuck at 100%. I assume its network interfaces are also a bottleneck as well. Certainly if they are 1g. Y.
