Casper Admin DP sync super slow

Valued Contributor

JSS 8.73, Casper Admin running on 10.6.8 Xserve. 12 Mac OS DP's, manual sync as needed, not auto.

I'm recently noticing that when I perform a DP sync with Casper Admin, it's glacially slow. 10.9.2 update didn't complete to even the first DP overnight.

However; if I log into the JSS, mount the CasperShare of a DP and do a simple drag-n-drop file copy- it completes in normally reasonable amount of time.

I was going to complain to the network guys, but I get normal throughput manually. Anyone?

When you use Casper Admin, you are adding an extra network hop to the Admin system (the files are copied from A to B via C instead of straight from A to B), and if your primary DP is not at the same location then that will slow things down quite a bit.

You want your Admin system to be as close to your backbone as possible, ideally on the same LAN as the primary DP.

yes, Casper Admin is running on a Mac right next to the JSS, both physically and logically switch-wise.
First time in 3 years I've seen this.



So when i copy a large file using Casper Admin, it copies the file to my jss (which is a linux box with a reasonably low amount of ram and diskspace) then copies it to my smb fileshare?

I am seeing very spiky upload speeds when syncing using Casper Admin and when copying files up to the Fileshare from my desktop so could this be to blame? I see speeds from max to a couple of kb then back to max every 3 or 4 seconds.

i have studied the load on the jss while doing transfers using Casper admin and I do not see an increase in disk or network activity.
