netware 5.1 maximum physical packet size

[rcne]

we upgraded our servers from 4.11 to 5.1<br>old packet size was 1514 for ethernet, default is now 2048.&nbsp;&nbsp;why? <br>performance is slower how to optmize.<br><br>we used optimized autoexec.ncf from 4.11,<br><br>what is new in 5 that i need to look at

Well, first off the 2048 is a setting that is required as a buffer for building packets.&nbsp;&nbsp;As far as performance goes, this would not slow the server.&nbsp;&nbsp;What you want to do is increase the following:<br><br>Maximum Packet Receive Buffers to 4000 (or higher)<br>Maximum Directory Cache Budders to 4000 (or higher)<br>Minimum Service Processes to 100<br>Maximum Service Processes to 1000<br><br>This should improve the performance.&nbsp;&nbsp;However, on the support.novell.com website, you can do a search for performance tuning and optimization, and go through the 2 documents.<br><br>Also, make sure you check that file compression is run after hours.&nbsp;&nbsp;this would affect performance as well.<br><br>There are other tuning settings that the TID's cover and you will just have to compare the tid to y our environment.<br><br> <p>Mark C.

I checked the performance tuning in the CNE net, will also verify these other settings,<br>performance is improving, but never goes as quick as i think it should.<br>I also am a CNE since '92, got my 5 cert in feb, good luck

I took some time and was reading the NW 5.x update book, and in it I found an interesting blurb.&nbsp;&nbsp;If you increase the Maximum Physicial Packet Recieve Size, this should in turn, increase the performance of the server.&nbsp;&nbsp;This is a buffer setting, it does not restrict the size of the packet, but allows the server to have a place to store packets as they arrive.&nbsp;&nbsp;You may want to also try douling this from 2048 to 4096 and see what happens.<br><br> <p>Mark C.

mark tried the packet size update will let you know if it has the desired effect. here's some additional info, running netserver dual processors, with ipx and static ip, this netserver has the hp pci netboard, i've seen some items on this chipset, if all else fails i might replace this board with a netgear.<br>thnks<br>rcne

Hmmm, I have no other info at this time.&nbsp;&nbsp;How's the testing coming along? <p>Mark C.
