How good is Gluetun at handling tens of concurrent proxied requests?

[javierlopeza]

Hi there! 👋

First off, I want to say thank you for all the great work on Gluetun—it’s been a wonderful finding!

I’m curious about Gluetun’s performance when handling multiple concurrent proxied requests. Specifically, how well does it manage tens of concurrent proxied requests at the same time?

For example, I tested locally with 4 clients connected to the same Gluetun Docker instance. Each client is making many requests per second, and I'm using the Gluetun HTTP proxy. When I create a second Gluetun instance (making sure the NordVPN server IP it connects to is the same as the first instance), and connect 2 of the 4 clients to this second instance, I see the overall bandwidth for my clients almost double.

Are there any best practices or limitations I should keep in mind when setting up Gluetun for high-concurrency scenarios? Would you recommend scaling Gluetun instances this way for better bandwidth?

Thanks a lot, and I appreciate any insights!
