MSMQ behaviour

Hi,  I'm using EV10 SP3, Exchange 2010.  We have 2 EV servers, one journaling one for users mailboxes, with separate SQL 2008 server.  Last night we enabled 100 people in EV, the first of our pilot g...

    Where have you placed the MSMQ storage location? Is it default location? We recommend moving the MSMQ location to different drive than the system drive.

    I found following information in Performance Guide.

    Archiving generates IOs on local disks. The primary causes of these are
     The creation of temporary files used when archiving and conversion
     IOs generated by MSMQ
     IOs to the Enterprise Vault cache location.
    To isolate the IOs that MSMQ and Enterprise Vault cache cause, place the MSMQ files and the Enterprise Vault cache on fast local disks separate from the system disk and from each other. MSMQ is used during Exchange archiving and journaling but not for File System Archiving, Domino journaling and Domino mailbox archiving, PST migration, or SMTP archiving.
    Blade servers generally have slow local disks that are not suitable for high IO loads.

That's not true at all

the item goes from A2 to storage archive, once it's been archived it goes to SQL in to watch file and scans for backup, after backup is detected it posts the item to A1 and then goes ahead and turns the item in to a shortcut

but you could be right that it was a backup that occurred and it posts 490k items to A1

what I would suggest is setup perfmon and add the EV msmsq's and find out exactly which queue is causing the io
