Opening powerpoints over VPN significantly slower

Hello EE,

I have a user who can open powerpoints in 20-30sec on the network, but over VPN it takes 3:50 seconds and often errors out that "The directory name is invalid" or "could not open....."  

Any suggestions to improve this?  We use checkpoint vpn

His contract with his ISP probably gives him a low bandwidth connection. Upgrade this for a faster connection.

Or if he is connected via wireless, he might be too far away from his router...

He ran speed tests and has no issue unless on VPN and email works fine it's just file share access
That's what usually slows you down most when you have a slow connection. Email seldom is a problem.

How can I best test it without saying its yor connection at fault.
First check what product from whom he is using. Most ISP's have different offers and they publish what speeds those different products have. Many have a relatively high download speed, while the upload speed is very low. VPN connections will slow down a lot if the upload speed is low.

Thank you Rindi I thought there was something with the upload, but can you explain more as I am inquiring with his ISP, but will need to be able to elaborate given his argument is I'm opening a file on the network share so it's download
For VPN and normal network access you need fast internet in both connections, as data movesboth ways, to the remote PC and back. When you work on a file remotely it first is downloaded to your PC, you then work on it, and after that gets uploaded back to the server. It's a different issue if you were using something like remote desktop, where only the mouse, keyboard actions and display info is passed through the internet, that is very little data. The files themselves stay on your servers aren't copied back and forth.
