Very slow index

Hi to all,

Sometimes my e-mailxtender index very slow, very, very slow. I have to stop Journal to down private queue Index but, sometimes I have use "readmsmsq" and send items from this queue to txt file.
I have modify the key "Maxnumindexprocesses" in windows Registry to 6 but this is not the solution.

Can I accelerate the Index?

I have 8 Gb to RAM

Thanks for advance

    How is your processor utilization?

    Usually, the indexing process is more processor intensive.

    Hello Pit

    MaxNumIndexProcesses should not be more than 2x processor cernels (= 2 x number of processors you see in the task manager > Performance). Unfortunately for you, the amount of RAM doesn't help.

    under Programs > Legato EmailXtender > Support > EmailXtender Performance there is an indicator for the processor utilisation.

    This'll give you the insight of what the processor is busy with. -> I only get more than 50% utilisation if reindexing some volumes. Otherwise this service has only peaks around 30%.

    Are the disks for the index fast enough; are they keeping up with the load?

    Hope this helps. Don't mind getting EMC support involved. They are good in tuning a system.

    Regards,
    Jochen.

    Hi Jochen Köcher


    I have 8 processors. Can i put 16 as max in "maxnumindexProcesses"?

    In EmailXtender Performance, what is the instance to processor use?

    Regards and thanks

    Hi Pit,

    wow, 8 processors (probably 4 physical?) is quite something. What physical hardware do you have? Well, you can try changing the MaxNumIndexProcesses to 16; though this sounds high. If you have had 6 before, you might want to start with 12.

    This value will allow more processes, but the system will decide to create/use them. My MaxNumIndexProcesses is set to 8, but see only 3. Only when I had a corrupt index and need to reindex a lot, this will increase over time (some minutes). - exIndexSrvc is the service, but the exIndex, exIndex#1, etc. will do the work.

    Sorry, don't understand what you mean by "what is the instance to processor use". There you'll see how much processor utilisation is required for each service/task.

    Does this help? Regards.

    Respect to "EmailXtender Performance", I have understand.

    thanks.
