Poor spooling performance

Hello everybody,

we have introduced iPrint Appliance 2.1 with PaperCut MF 16.4 on top about 6 months ago. Since then we observe very low speed rates while spooling printjobs to the Appliance. We use Windows 7x64 Clients (1GB LAN, SSD) with iPrint Client 6.06. Actually we have an SR open with Papercut because of an issue with long delays when a user releases a printjob at a hold/release queue to a physical queue (which is simply a mv from one folder to another). PaperCut says that we should first solve our slow spooling issue, before they continue investigating the Follow-me print issue.
So my question to anybody who uses iPrint Appliance 2.1 is: what spooling rates can we expect? In my case, i reach only 1,5 MB/s! This means for example, a 120MB spoolfile (which is rendered from a 19MB PDF) lasts up to 80s until it is fully spooled. If this is too poor, where can i start my investigation? Network and filesystems are ok. I did a manual copy of the spoolfile from client to server, which comes up to 25MB/s. The slowness is only while spooling a printjob via iPrint.

Thanks to everybody who can help!

Cheers
Manfred

Blind guess, check apache performance. There are some tids to improve
apache speed for iprint as tid7018252

A lan tace may help do identify the slowness as it may be on the path
between ipsmd and papercut daemon.

You can create a printer with no papercut auditing enable so from
appliance directly to printer and see if slowness is present. also a
printer configured as iprint direct, so from Pc to printer directly
bypassing iprint appliance and see if there are any differences in speed
when printing the same file

in this link there is a white paper about 1.1 performance. It is almost
the same for 2.1 so you can get a good idea about appliance performance.
