High-Speed TAP (driver) in Windows? #1096

Closed bluesky2319 closed 1 year ago

bluesky2319 commented 1 year ago

Question: Is there any alternative to OpenVPN TAP in Windows? OpenVPN speed is limited, and based on my test is around 250-300Mbps.

The desired speed is 800-900 Mbps.

There is not currently any other option on Windows. I am interested in what your use case is though?

Thanks for your reply. I have access to high-speed internet (1 Gbps), and when I use n2n my speed is dropped from 850-900Mbps to the lower numbers. I read in some forums which Wirequard or NordVPN have higher transmission speeds, they support more than 900 Mbps in Windows. Are there any other ways to speed up the transmission?

You can carefully select the encryption and compression settings that you are using to tune the speed for the hardware that you are using - have a look at the doc/Crypto.md document and the tools/n2n-benchmark test tool.

You can also compile with various optimisations to try and get more speed - have a look at doc/BuildConfig.md for some starting points.

However, none of these are going to change the tap interface - so if you have correctly identified the OpenVPN TAP interface as your bottleneck, it will not help your situation.

Some testing and benchmarking is definitely recommended - and we would be interested to hear what kind of speedup percentages you manage to achieve - I dont know that anyone has spent the time to write down benchmark results
