Slow connection through OpenVPN 2.4 + Firebird 2.5

[lucascatani]

Hello.
I have a connection speed problem in FIREBIRD 2.5 through OPEN VPN 2.4.

The system behaves extremely slowly in SQL queries. My configuration looks like this:

OPENVPN SERVER (Ubuntu 18.04.5 LTS - OpenVPN 2.4.4 x86_64-pc-linux-gnu)

SERVER UPLOAD CONNECTION: 100Mb/s

CLIENT UPLOAD CONNECTION: 100Mb/s

The question is how do I increase performance?

You are using --dev tap, completely incorrectly.

You are using --dev tap, completely incorrectly.

it doesn't tell me anything. If you can talk about your answer it will help me, if not, it looks more like a guessing game than a collaborative answer.

When openvpn running over TAP it will slow down as much as many pc connect to it openvpn server. that is because all computer broadcast all its existence on that subnet and the more pc on the slow it get. you need to change to tun so it run on routing it faster and you can expansion it more simple.

up load speed 100 mb shoud get you 60 mb upload easy so should be very fast not slow at all .

Hi, the result is the same: SLOW on FIREBIRD.
