How To Fix Slow SSTP RRAS VPN on a Citrix XenServer Virtual Server

Ever since moving to Windows 10 and Windows 2012 R2 we've seen a serious drop in performance when using SSTP (Secure Socket Tunneling Protocol) on our Windows 10 machines. After weeks and weeks of troubleshooting, we believe we have the issue narrowed down to some NIC and registry settings on the RRAS (Routing and remote Access).

NOTE: This is for virtual servers that run on Citrix XenServer. Some of these things may be different in your environment...

The first thing you need to do is go into the device properties of you NIC and select the configure button. Under the Advanced tab disable all of the "offload" settings.

The next thing you need to do is make the following registry changes:
  • Set DWORD value EnableTCPA=0 in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
  • Set DWORD value DisableTaskOffload=1 in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
  • Set DWORD values TcpAckFrequency=1 under every interface GUID under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces
  • Reboot 
After doing all of that we saw a significant performance increase in file transfer speed and general network performance.

Give it a try, and let us know in the comments if it worked for you or not. If not, let us know what you had to do differently!

Bauer-Power Media Launches a New Podcast - Mainwashed Weekly Scoop

It's been a few years since I did any kind of actual show. As some of you know, I used to do Tech Chop weekly on The Tech Podcast Network. I stopped doing that because it started to become a full time job writing scripts, coming up with content, filming and editing every week. I never lost the bug though!

Well, recently I've been listening to a lot of audio podcasts and thought, I could start doing another show, but this time just do an audio only podcast that folks could listen to while working out, during their commutes, etc. I also thought it would be easier to come up with content from the news, and since I mostly read political news for my Mainwashed Facebook page, I thought why not do a political podcast? I also decided to do this one off the cuff, so there is no script to write every week. Editing a show takes about 20 minutes of my time max!

So, this last Tuesday I kicked off the first ever Mainwashed Weekly Scoop show where I give my unfiltered take on some of the national and world political news I see all the time. I say unfiltered, because I used to be a sailor and like to express myself with colorful words every once and a while. That being said, this isn't a news show for kids!

It's still brand new, but I'm planning on posting a new episode every Tuesday. Right now you can subscribe directly from www.mainwashed.com, but I've also submitted it to the following Podcast sites:
If your political views lean a little right, but still consider yourself a Libertarian, then you should check out the show. If you are a granola eating, left leaning Communist, then you should probably stick with MSNBC.

Give it a listen, and let me know what you think!
