VMs - Slow transfer Tags: Virtualization Servers Business Computing Last response: August 22, 2012 7:18 PM in Business Computing Share botox76 August 22, 2012 1:30:40 PM Hi all, I am using VSphere 4.1. Everything is on GB, (ESX, SAN , Switches etc) If I copy one large file between servers or my machine to server I am getting 100MB/Sec + However if I copy directories containing 1000's files between the same servers, I am getting between 3MB and 6MB per second. I understand copying smaller files will always be slower, but surely this cant be right? Ive also tested between my PC and a physical server and everything is fine so Im sure it must be Vsphere or SAN setup. Does anyone have any ideas?
