will running multiple Jenkins masters on same host increase the performance

Question

Suppose I have to run dozens/hundreds slaves on one machine. Is it better to set up multiple Jenkins masters on the same host to increase the efficiency and performance? Or should I use a big master instead of using multiple small ones? I am curious to know this.

Thanks.

Answer 1

I think one big master will always be better.

If you want to install plugins, run maintenance server, keep back up and upgrade and perform other management stuffs, it will be easier to do on one big master rather doing it on multiple small ones.

I hope that it will help you decide which option to chose.

Answer 2

While using one big master, u can expect several problems related to file lock. Also you will be losing more ram because of two different Jenkins. I tried running 2 Jenkins in a machine it was really slow comparatively.
