### Factors
|

- The further away the VPN server is, the slower the bandwidth will be

|
- Running Docker on a VM/Windows/OSX brings a serious bottleneck due to virtualization
|
||||||
- Some VPN providers seem to throttle down the bandwidth when you run a speedtest (e.g. Mullvad)
|
- The VPN protocol (`VPN_TYPE=openvpn` or `VPN_TYPE=wireguard`) have very little impact. Wireguard does have a more significant impact on low power devices though (+15% speeds).

- Bandwidth fluctuates during the day due to other VPN clients on a particular server

- Bandwidth fluctuates during the day due to other VPN clients on a particular server
|
||||||
|
- Some VPN providers may:
|
||||||
|
- throttle down the download bandwidth when you run a speedtest (e.g. Mullvad)
|
||||||
|
- allocate you less bandwidth if you don't use their proprietary software
|
||||||
|
|
||||||
### Things that don't make much sense
|
### Investigations
|
||||||
|
|
||||||
- Only when the VPN server is far away, gluetun is x4 slower than native openvpn
|
#### OpenVPN
|
||||||
|
|
||||||
### Additional notes
|
- Only when the VPN server is far away, Gluetun's OpenVPN is x4 slower than native openvpn. This might be due to OpenVPN being built for `musl` or due to other libraries such as `openssl` built for `musl` (Alpine).
|
||||||
|
|
||||||
- On native Docker, CPU cannot be the bottleneck since we reach 500Mbps with gluetun on a nearby server.
|
|
||||||
- Gluetun runs `openvpn` installed with `apk add openvpn` and not a custom implementation. One difference that could have an impact is that it's compiled with `musl` instead of `glibc` to be compatible with Alpine, and `musl` is know to have slower raw performance.
|
|
||||||
- Subscribe to [#134 Support for Wireguard](https://github.com/qdm12/gluetun/issues/134) as that might help increase bandwidth, although the implementation will be in Go and not in Kernel space.
