[vpn-help] Windows 7 64bit Slow VPN

[Mark A. DeMichele]

I meant to say, "I don't blame you", not "believe you".  Sorry.

I don't believe  you for being skeptical.  I'm a programmer and I
understand where you're coming from.

I just did as you requested and was very methodical about it.  Here's
what I did.

1. Using the 2.2beta2 version, I uploaded using a VPN address and then
again with a public address outside the VPN.
	VPN Upload Speed: ~450KB/sec.
	Non-VPN Upload Speed: ~550KB/sec

2. I uninstalled 2.2beta version and installed 2.1.7.  I used the same
profile  (it's nice it remembers all that between uninstalls and
installs BTW). Same urls and same files to upload.
	VPN Upload Speed: ~12KB/sec.
	Non-VPN Upload Speed: ~550KB/sec.

The higher rates vary a lot +/- 50KB/sec., but the slow VPN rate is just
pretty slow.

I had tried 2.1.6 the other day with the same result.  I hadn't gone
back any further since the 2.2 fixed the problem.  Also both of my
Windows 7 64 bit machines seem to have this problem. Maybe it's router
related?

I have a Belkin N600HD router.  

   Hardware	F7D8301 v1
   Firmware	1.00.30 (Dec 24 2010)
   Boot Loader	1.08e

Thanks for the update Mark.  I'm glad it's working faster now, but I'm
not sure why.  I don't recall anyone complaining about performance of
2.1.x on Win7-64bit on the list before now.  Are you interested in
downgrading to 2.1.x on one of those machines to see if the performance
problem re-occurs?
