Is concurrent_compactors dependent on physical or logical cores?

Hi there!

I'm a novice at cassandra and have a question regarding concurrent_compactors setting.

I've found this information on "cassandra.yaml configuration file" page:

"If your data directories are backed by SSDs, increase this value to the number of cores."

Does the article say about physical cores or logical?

Thanks.

It's based on physical cores. Setting it to logical cores would saturate the CPU on the servers and will have the opposite effect. Cheers!
