Performance question

[organman]

I have just upgraded a NW 5.1 Pentium III 933 MHz, 1 GB RAM server to NW 6.5 SP3.
This server is also running Groupwise 6.5.3.

I have a trusted application running on this server that connects to our PBX for calendar sync.
This application is somewhat heavy for the server, taking a lot of CPU power.

After upgrade to NW 6.5 this server seems to be running slower than it did with NW 5.1.

I notice that in the Groupwise clients it takes longer time
to fetch messages in Sent Items and Inbox than it did before
the upgrade.

So what shall I do about this ?
Right now I can't switch to new server hardware but I can
install a second CPU in the server and add more RAM.

Would adding another CPU and double the RAM cure my problems ?

NW6.5 is a lot heavier than NW5.1. Needs lots of horsepower.

Adding Ram would definitely help. 1GB is barely enough to run base services correctly. And you're running GroupWise and that other application.

Another processor may help a little but it's not going to be dramatic. Certain things may benefit but in general, you can count on most things running on the first processor anyway.

Another consideration... You say you upgraded.. Did you upgrade on the same box? Do you have a mix of NSS & Traditional volumes? That will affect performance because the server has to allocate RAM to both file systems. Better to have all Traditional or all NSS.

A standard server I setup for my customers to run NW6.5 is 2 to 4 gigs, as Marv points out, 1 gig just doesn't cut it.

In the mean time, you can also go through the services that load by default. You can rem out the tomcat and the apache modules (the two biggest resource hogs on NetWare 6.5). Just note, you will loose web services like iManager when you do so. The lines to look for will be;

ADMSRVUP
TCADMUP
AP2WEBUP
ADMSRVUP
TOMCAT4

You can also dump EMBOX and NDSIMON if you have no need to monitor and configure NDS (most IT has no need for this).

You can also rem out PSA (Posix Semantic Agent). This only does iManager exceleration.

While your at it, you can get rid of Pearl since your disabling web services.

Also, if your using any remote console apps built into netware, disable them. RCONSOLE is a resource hoge (and runs on IPX), RConJ is alright, but can hoge resources on connection. Go out and download FreeCon from AdRem, it rocks.

If your AntiVirus is running and scanning incomming and outgoing, disable outgoing. If it's on the server, you can be sure it's clean and it's pointless to scan files as they get pulled from the server.

If this is a compaq server, rem out the stupid CPQ NLM's. Only usefull one is CPQHEALTH to get the fans in the server to shut up.

Ahem. Perl can be used to create CGI apps for your webserver, but that is a small feature of this extraordinarily rich scripting language. My instances of Perl only consume 64k of ram (yes, that's kilobytes).

Turn it off if you're not using it, but you may want to use it. I just love the stuff.

If you have GroupWise Webaccess on that server you'll need apache and Tomcat. Otherwise you could disable them.

OK, I'm using GW webacces on this box so I can't get rid of apache etc.
I'm only using traditional volumes.

So I guess the best way to go is to get the server up to
at least 2 GB RAM and maybe add a second CPU.

my 2c I have a 2 node groupwise cluster. 1 node has 2 cpu, 2nd has 1 cpu. Both have 4GB RAM. I don't notice the 2nd cpu in normal operation even when I fail the whole system onto 1 box. It helps with indexing jobs etc, but does add complexity (you open yourself up to any SMP code bugs/issues).
There have been some notes on the boards about GW servers having issues with >2GB of RAM. Something to look at. I would personally max out the ram if budget allows. Make sure your network connection is happy (check speed, duplex, coll, FCS errors, etc) as that will do more to your speed than anything else (save the storage system/controller & drives). Also go to NSS volumes (I think you said you're on trad?) and make sure the volumes have a decent amount of spare room.
