iManager so Slow!!

Hello, we about 10 VM servers running SLES 11sp1 and OES11, 8GB RAM and 2CPUs. Anyway, I manager 2.7.4 is so slow in all servers, it takes about 5 minutes to load in IE or Firefox. Then Changing pages takes a few minutes too.
I been googling for a while but no luck, I don't even know how to start troubleshooting.
Anybody have the same issue?
Any help greatly appreciated?

    Hmm, iManager is actually pretty fast (once tomcat initializes here). Both OES2 and OES11
    But you don't mention if the requirements/hardware you listed is for each VM or is that total for the ESXi Host it's on (assuming Vmware)?
    If it's vmware, have you installed the vmware tools?

    I've got a VMware Guest for OES2 SP3 32-bit with a measily 512 MB of RAM and iManager runs much faster than what you describe.
  • Each virtual server has 8gb RAM and 2 CPUS, and yes I Installed the VMware tools. Maybe it is something wrong with the our network

    There are a number of performance issues related to TCP Offloading.
    Search the knowledgebase for "offload".

    No guarantees this is your issue but it's something to check.

  • do all your edir servers reside i nthe same subnet or location?

    i've found with one place I look after that imanager is dog slow (10 mins to get it logged in...) - this is because we have no local replica of the server and it's objects (don't ask) and imanager seems to need to cross the wan link to get going

    maybe a trace on edir trafic might shed some light on whats going on, or simply looking at your network stats on the linux boxes to see if you have any errors there too

    if you install imanager on a windows workstation and try some things from there, does it still perform slowly?
  • Hi, Thank you for the reply, yes all the server are in the same Rack in the same subnet. I am beginning to think KBOYLE's suggestion: TID 7009616
    Virtual SLES11SP1 shows bad IO performance when accessing raw disks
    Support | Virtual SLES11SP1 shows bad IO performance when accessing raw disks

    Could be the problem. All the servers with the imanager slowness issues have terabytes of SAN storage attached to them. I have a couple of servers that don't storage attached and imanager is fast!

    I added a replica to the one server and still slow. Weird

  • Hello again, I mentioned that I added a replica to the server with the slow iManager, I never restarted Tomcat(I thought I didn't need to) so I did and iManager is normal now!! Thanks for the hint!

  • I thought putting a replica on the server fixed but is back to normal "very slow"
  • We have the same issue with 3 different servers running iManager. Login takes 3- 5 minutes, it's ridiculous. All three servers have replicas, all three are xen-based virtuals. They also have SAN disks, but only for the NSS DATA volume, the OS itself (from which iManager runs) is on local disks (blade server) so I doubt messing with the scheduler would help much here.
    We also noticed that iManager is fast for a brief time after restarting tomcat, but after a day or two, it's logins slow back to a crawl. We never really had this issue until we had more admins stop using ConsoleOne and start using iManager, so it seems to be sort of a load issue.

    What OES version?
    What iManager version?
    What is the amount of RAM in the DomU? I'm assuming para-virtualized?
