I have my CM running in a VM on my C210. Switch detects auto/1000, no errors. When uploading new cop files via ftp (OS Admin) it takes a crazy long time to complete. A 384 file took over an hour. That same file, to a different server at the same location, took about 35 seconds.
I looked at sniffer traces and don't see anything except a few re-trans... The rest is just data/ack, data/ack.
I looked at the VSphere Client and don't see anything weird, but my VSphere kung fu is weak.
Any thoughts on what I can look at? Network is good. I know it's the CUCM box.
I've been having this same problem. Speeds to other VM's around the CUCM VM are fine. In my case, I'm running 8.0.3.. The interesting thing about this is that once every 4 minutes or so, I get a large burst of traffic through (about 3-4MB/sec) for about 5-10 seconds, then the speeds drop back down to almost nothing (a few KB/sec).
Under normal operation, I don't see any performance issues (spotty/dropped calls, slow management interface, etc) with the CUCM servers.
I wish I could rate this for you guys, but the Disabling LRO Fix corrected the issue for me. Running CUCM 8.5 on a UCS C210. Before my transfer speeds were averaging 6.4Kbps with two second jumps to 40Mbps every few minutes. After this my transfer rates were averaging about 140Mbps. Thanks guys!

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
