I have an update on this. For the heck of it, I installed version
2.2.0-beta2. That seemed to fix it, or at least made it much better.
I now get about 400KB/sec from both 64bit machines.

Subject: [vpn-help] Windows 7 64bit Slow VPN
I realized that my upload speeds to my office over our VPN were very
slow so I started digging into it. At the office we have a Netscreen 10
hosting our VPN connections. On one of the servers at the office we
have a nice HTTP based file server that I can access remotely using a
public IP address (no vpn) and a local IP address (vpn), and when
uploading it displays KB/Sec. This gives me the ability to compare
upload speeds.
Also, at my remote site (home - Comcast cable), I have several different
machines behind the same router running different OS's. These are the
machines.
Two Windows 7 64 bit machines
One Windows 7 32 bit machine
One Windows Vista 32bit machine
All the machines have Shrewsoft 2.1.7 installed using the same config.
I tested all them without the VPN and they all uploaded at about
550-600KB/sec.
On the Window Vista 32bit machine, I tried both Shrewsoft and my
original Netscreen client. They both performed ok at about
450-500KB/sec. (Slower than without VPN, but I guess that's expected).
Same results as above on the Windows 7 32 bit machine.
However, on both the Windows 7 64bit machines, I'm only getting about
12KB/sec which is painfully slow.
A co-worker at another remote location using Windows 7-64bit and
Shrewsoft 2.1.6 can upload at about 550KB/sec. I uninstalled my 2.1.7
version and installed 2.1.6, but I get the same results, so I don't
think it's 2.1.7.
Can anyone give me some pointers on where to look to figure out why it's
so slow.
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?
