build-agent process priority

Hi everybody.

I wonder how heavy the build processes are on the cpu..

I set up a single machine offering many different services (also including teamcity webapp and teamcity buildAgent) and I'm worrying a bit about overall performance when the teamcity agent will enter production stage.

Being a virtual machine, I will be able to add one virtual cpu if the load will be too much.. but I wonder if it also possible to set some configuration option so that the build processes are started with a high nice value. Another option I can think of would be to start the build-agent main process with a nice value, but I don't know if that will be considered when the agent will span the build processes.

Could anybody please cast some light on this?

Thank you and best regards.

Hi Roberto

Any performance metrics are very subjective, as they depends from your type of builds.
But usually builds are CPU-demanding, and consume all available resources.

I would recommend split TeamCity server and build agent on separate machines, and add more resources to the build agent machine.

Also, take a look at Estimate hardware requirements for TeamCity article.

Thanks
Michael
