Hi everybody,
at the weekend we try to convert an hardware-server to an esxi-vm. The vmware-converter converted the host and the vm starts fine on the esxi-host. All applications on the system works, but one application is extremly slow. It ist an asp-application using a iis-webserver and an access db using odbc. All reading request are fast, but all writing-processes are extremly slow.(3-5 minutes instead of some seconds) The systems runs windows 2003 server with an IIS and an Access 2000 DB. The esxi-Host runs version 5.

best regards

Here's a few suggestions, in somewhere near 'most likely' order..



Have you tried a 'Compact and Repair' on the access DB?

Have you checked if the Web App is being throttled in IIS by 'number of visitors perday' or Maximum Memory usage?

Have you checked that the Virtual Memory settings of the Guest VM server are correct (i.e. not disabled)?

Have you installed the VMWare Tools on the Guest yet - Have you tried going Device Manager on the Guest and updating/checking the Hard Drive Controller drivers?

When you migrated, did you choose a IDE or SCSI drive (emulation) and/or did you use Dynamically Expanding Disks - if the latter then just filling up the drive on the guest then deleting it might improve things a little.

Check in ESXi/VMSphere that you havent inadvertently throttled any resources to the Guest.

Perform a CHKDSK on the C: - especially if it is on a FAT32 files system (i dont think thats possible on 2003 server but it's still worth doing a chkdsk anyway)

Consider Defragging the Guest Operating System Hard Drive.

If the ESXi host is running on a hardware/motherboard raid - especially a 2+1 IDE RAID5, are all disks definitely OK (i.e. check at Controller/BIOS level) - a rebuild on a RAID5 can be painfully slow (especially during a write) if the disks are busy reading/writing as well.
