VPN speed issues

10-28-2009 4:04 PM

Hi - we have been using VPN to conect our branch offices to our server and while it works ok and is fairly transparent the big issue we are facing is speed, its just really slow when uploading documents. Hence my team are reluctant to use it that much.

I am no tech head but are there ways to improve transfer speeds over VPN?

We have the best possible broadband at all offices ( well best we can get in New Zealand) 200- 1000 KBs up and 4-10 Mbs down.

Hi Richard,

What are the size of the files that you are trying to access across the VPN?

What is the other Internet activity consuming bandwidth of your connection?

If there is allot of Internet surfing, Video and streaming radio, you could be loosing the bandwidth that you need for the VPN.

Does your VPN equipment have any traffic shaping and priority handling? 

You may benefit from an outside consultant to see if you are set up optimally.

On my VPN I used the bandwidth optimization feature which improved my performance greatly.

Richard, your choke point is your upload bandwidth.  Any VPN connection at 200kbps is going to really annoy users.  Also, keep any eye on streaming video/radio from all the sites.  Dave gave you some good advice to check out.

Is there a business class service from your ISP that maybe costs more that has better upload bandwidth?
