Question about "server-count" config option

NSD
1

Hi there,

I have a question about the "server-count" option. nsd.conf(5) simply states that it tells NSD to "start this many NSD servers", with no further commentary.

Is there a situation where this value would ever be anything other than 1? Should it equal the number of available CPU cores?

Cheers,

Hi Gavin,

Yes, the usual practice is to set this value to the number of cores
available.

Do you see improved performance when you increase the server count equalling to number of cores available ?

We are running in a Virtual environment and actually saw a decrease in performance by half when testing with queryperf. We used the sample data set and have yet to see the result using a real life captured dataset.

Thanks.
