Due to a performance problem with Samba, I encouraged all my users to switch to Microsoft's WinXP LPR, only to find that it was taking a factor of five longer to send print jobs to the server. Here's what's happening:
An LPR transfer from Linux consists of a steady stream of packets with 1460 data bytes each.
An LPR transfer from WinXP LPR consists of groups of 21 packets with 1460 bytes followed by a packet of 1340 bytes with the "push" bit set (total bytes = 30,000). The server responds to the "push" bit by waiting .2 seconds before sending an "ack". All these waits slow the transfer down by a factor of 5 (on a 10Mb net).
This is covered in http://support.microsoft.com/?kbid=816627 (ie. "Be happy, it used to be worse").
I would like a high quality alternative to Microsoft's LPR. Since our out-of-band Kerberos authentication method is likely to go away soon (because of NATs), I would _really_ like to have Kerberized LPR.
Any suggestions?
