This is good for the Tor process itself, but disadvantages other processes. If your server is doing name resolution (as an exit node) the resolver may be impacted, which in turn will hamper handling of exit traffic.
Renicing to a positive value decreases the priority of a process, not increases it. Tor at +10 will not affect any other processes, except maybe "completely idle" priority ones, which get +20.
