Is NE performance better than OSS?

[Dragon]

Is the NE version performance better than the OSS version? I'm currently running a server for 5 people, and the web client just seems to lag a bit.

Here's my hardware:
Dell 1750
Dual Xeon 2.8Ghz
2GB RAM
2x 36GB Scsi drives 10K RPM mirrored.
100Mb connection to the Internet
OS: Ubuntu 6.06LTS

I've checked my network settings from the server all the way to the Internet, and I'm not having any issues there. Everything on the Zimbra install works. The evite zimbra still doesnt sync calendars, but that's a mute point.

Zimlets installed: amazon, arcade, collector, date, email, evite, gtranslator, phone,rss,search,tracking, travelagent, url, xslt, ymaps,ytraffic.

What I notice is that switching between tabs (Inbox to calendar or contacts) there is a 1 or .5 second hesitation. I've tried logging in and out serveral times so that way I know everything is cached and its not loading for the first time. Which, when loading for the first time takes a very very long time.

I read in the other thread that Ubuntu 6.x lts is a supported OS. So does the NE version run better? Are there performance enhancements in that one vs the OSS version?

Thanks for the help and clarification.

No, performance should be exactly the same as they are the same code. Have you disabled IPv6 on that machine?

You don't say which version you're running, more recent versions have better performance but I guess yours is fairly recent as you're using Ubuntu.

hmm no, haven't disabled ipv6, I take it, its on by default? Let me search for how to turn it off, or if you post here, I'll go turn it off and tell you my results.

It shouldn't make that much difference but we recommend it be off, here's a few links.

I really think that you're probably seeing a normal response, there is a lot of code there to switch between tabs and redraw the correct screen.

Just out of interest, try undeploying the Zimlets and see if that makes any difference (don't forget a tomcat stop/start).

What are your client computers ?
Which CPU, RAM, OS and browser ?

I bet the problem lies there (client computers), not the server (as usual).

I did turn off ipv6, and it was a hair better, but still seems hesitant.
I'm trying from a few different computers, their specs and info are below.

Computer 1:
Laptop: Pentium M 1.5Ghz with 2GB of RAM,
Browser: Firefox 2.0.0.3
Connection: T1 1.5Mb - point to point to where the server is
OS: XP Pro

Computer 2:
Dell Dimension 9200: 2Duo core 2.13Ghz, 2gb ram
Browser: FF 1.5
Connection: DSL - 3 meg down, 256K up
OS: XP Media Center

Computer 3:
Clone computer: P4 3.0Ghz, 2Gb ram
Browerr: FF 2.0
Connection: LAN - 100Mb
OS: Windows 2000

Computer 4:
AMD 2800+, 2GB ram
Browser: FF 2.0.0.3
Connection: 5Mb down 1Mb up
OS: XP Pro

Computer 5:
AMD 64 3200+ 2GB RAM,
Browser: FF 2.0.0.3
Connection: 5Mb down 1Mb up
OS: XP media Center

I need to get the specs off the other computers, but as you can see, its not like I'm using some old piece of crap to access the server. Computer 3 obviously has the best response out of all of them, but I'm supprised that over the internet the response isnt better. Even on computer 3 I see a very slight hesitation jumping from tab to tab.

All of the desktop clients are running just fine. No issues or laggyness on them. I really would like to figure out why I see a slight hesitation.

Yup, quite nice computers.

I see the same "hesitation" going from tab to tab with my old laptop (Pentium M 1.5Ghz, crappy Radeon Mobility), either on LAN or DSL (8Mbps/512Kbps).

And I've hit performance issues with Athlon 2800XP, 1GB of RAM (XP + FF1.5) but even crapier onboard graphic card (on motherboard).

I removed all the extra zimlets I installed from the zimlet-extras, and it definately performs much, much better. Sometimes slight hesitation, but I need to test from the other machines.

Once I test from my other machines, I see which zimlet(s) is making it slower. Maybe the individual zimlets need some performance tuning.

Good tip on turning off the Zimlets, that's actually what I was about to go do before I saw your post.
