Yes, WordPress (and pretty much any other major web application) needs to
make a DB connection, at least in the administration area. Some plugins
offer static page caching (Super Cache, Total Cache, and Batcache, to name
three), which would avoid a DB hit when the cache is primed.

Plugins such as HyperDB can divide calls across multiple databases, database
servers, or even data centers, and also across read/writes. That can help to
ensure that write or admin calls are always prioritized, etc.

As Dion pointed out, you're using a plugin that should probably never ever
be run on a read-intensive site. That's your problem. "Who is online"
plugins work better for something like forums and what not, which have a
much more balanced read/write ratio.
