VMware Converter Standalone 5.0 - Slow transfer rates

I've been noticing drastically slower conversion times using Converter 5.0 vs 4.3.  It turns out, Converter 5.0 encrypts the data stream using SSL by default.   This increased the security, but decreased transfer performance.  If SSL is not required, it can be disabled quite easily.

After installing Converter 5.0, locate the converter-worker.xml file: 

Windows 7 and Windows Server 2008 (R2):
C:\ProgramData\VMware\VMware vCenter Converter Standalone 
 
Windows XP and Windows Server 2003:
%ALLUSERSPROFILE%\VMware\VMware vCenter Converter Standalone

Make a copy of the converter-worker.xml file for safe keeping.  Then use Notepad to make the following change:

<nfc>
 <readTimeoutMs>120000</readTimeoutMs>
<useSsl>true</useSsl>
<!-- Delay is specified in milliseconds, -1 denotes the default.

TO:

<nfc>
<readTimeoutMs>120000</readTimeoutMs>
<useSsl>false</useSsl>
<!-- Delay is specified in milliseconds, -1 denotes the default.

Save the file, then restart the VMware vCenter Converter Standalone Worker service.  Enjoy the new found speed!
