The "free version" (ESXi/vSphere) is identical to the version you pay for, minus the manageability and failover/redundancy features. Are you talking about the nearly defunct VMWare server that runs on top of a base OS?
I've certainly noticed network latency issues on ESXi when system I/O increases. (Hundreds of ms jitter.) I figured this was the same with ESX as well, but there might be architectural differences between the two platforms which would make a difference. Or, maybe there's something else going on. Many ESXi users do use the local datastores, so maybe that's where the "enterprise has less timing issues" perception comes from -- if you're paying for licensing, you're probably using a SAN and vice versa. If using local datastores affects network I/O, "enterprise" users might sidestep this issue entirely. -Nick
