Fast Download / Slow Upload

[jonjon91 0]

I'm trying to get the most out of my upload speeds.

Are the airvpn servers noticeably slower at upload than download?

I have a 1gbps UP/DOWN via IPS. When using qbitt / gluetun on a linux server my upload speed is seriously lacking compared to my download speed. 

I've tried all sorts to improve this, with some success configuring SQM on my router to help with bufferfloat. 

Is there any additional tweaks i can make to improve this? Are the airvpn servers limited? 

I usually connect to Netherlands servers via airvpn.

Can hit really fast speeds download upto maybe 60MB

upload speed never seems to go beyond 15MB

Before i configured SQM it was more like 3MB max, on a really good day.
