It's a compromise, you are trading interactivity/responsiveness for raw
throughput.  It's like the difference between choosing the workstation
or the server timer for the Linux kernel.  An android phone and
high-performance SQL server have vastly different use cases.

I personally use the server (I/O sensitive) configuration whenever
possible on Linux servers.  However, as I've learned from Michal and
crew, things aren't always what they seem when comes to multi-threaded
workloads, I/O and caching.
