Question SSH Tunneling Lag Spikes

My knowledge has gone from newbie -> noob with understanding Linux, so any help would be appreciated.

I'm using a remote debian server to reduce my ping.

game -> my pc -> Putty SSH Tunnel -> Debian server -> Game Server
<-------Ping(350)-----------------> Debian server <-------Ping(9)->

Without setup - Ping 750+

Got it all setup, and working VERY well, the setup reduces my ping by 60%, however, every now and then theres a lag/latency spike for 30-60 seconds. Sometimes its quick, sometimes its there for a few minutes, then back to normal uber fast and quick.

During several of these lag spikes ive done some preliminary testing.

Tested on several games, happens in all of them

Test Data
Lag spike ping 1650-8000
Ping to server still 350
Ping from server to game server still 9

Therefore i can only assume that the latency increase is happening somewhere on the server.

I googled lag spikes and found this info:

The "software error" is due to the SSH daemon when it detects there is a problem with the user connection to the server and therefore drops the connection.
This can happen when there is a bad quality of connection between the user and the server (frequent request timeouts.. etc)
We've increased the timeout limit and will continue to monitor if the problem persists. Again.. Thanks for the feedbacks

Unfortunately as im still a noob, not sure how one would go about implementing this possible solution.

The best train of thought i have would be some kind of monitoring system in place to find what generating the lag.

Any tools or starting points would be greatly appreciated.
