CPU bound

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I notice that when restoring a DB on a laptop with an SDD, typically postgres is maxing out a CPU - even during a COPY.  I wonder, what is postgres usually doing with the CPU?  I would have thought the disk would usually be the bottleneck in the DB, but occasionally it's not.  We're embarking on a new DB server project and it'd be helpful to understand where the CPU is likely to be the bottleneck.

Cheers,

--Royce
