Transfer rate for updates when using sparkmanager

I couldn’t find anything that might be limiting the transfer rate of the update download, so thought I would ask…

I just pushed out the 2.5.7 update via sparkmanager. (Openfire 3.3.2) My clients are getting the message that the update is available and they install it just fine, but the transfer rate of the download of the update seems to be capped at 256Kbs even though they are on the same 100Mb Ethernet segment with the IM server. What should take all of a few seconds to pull down is taking a couple of minutes.

Is there a limit of some sort imposed by the web server that handles the admin tool? (http://imserver:9090) Is it adjustable?

Thank you…
