Basically have been working over the weekend converting a Single 2008 Server to the iSCSI ESXi 5.0 Environment (Fairly Straight Forward Right!) Well started getting serious speed issues and I know there is no performance problems with the server its converting from to where its going to. Just to show you how bad of a performance problem see this screenshot:
*Not a Pretty Site!
Anyway found this article which turns off SSL encryption between the host taking the conversion and the ESXi enviroment and the speed is 50x faster. Unfrotuantely I do not have a screenshot to show but next time I do a conversion I will update to show the difference.
Follow these steps to resolve:
Disable NFC SSL in the converter configuration file (steps from the converter release notes):
1) Disable NFC SSL 1.Open the converter-worker.xml configuration file. It is usually located in
2) C:ProgramDataVMwareVMware vCenter Converter Standalone folder.Set the key
3) Config/nfc/useSsl to false. Save the configuration file.Restart the VMware vCenter Converter Standalone Worker service
Note* Make sure you get the right UseSSL as its referenced under the use Soap Section as well:
Below is the speed increase when you do the above:
(This still not as Fast as I would hope but is better than what was previously stated – Also you should note this Server is heavy on SQL which I know has a big impact on the Conversion)
