vmotion and performance loss on VMs

Lately some people here have been complaining about slowness in an application running in ESXi 5.5. The app runs fine for a while then slows down to a crawl for a while, then suddenly works ok again.

Vendor is pointing fingers and saying it's not them, so people here are suddenly latching onto vmotions as causing the slowness, even though the timing of all vmotions don't coincide with the slowness issue.

The vmotions are handled on their own switch, on their own nic port. Performance stats for the VMs in question show nothing unusual, host stats same.

Does anyone know about a document about vmotion that I can use to stop these attempts to blame vmotion just because they can't find anything else? Has anyone experienced slowness or vms going off the network due to vmotioning?

Thanks

Matt
