<td>Currently, two schedulers are present: SCHED_ULE (default), an
SMP-optimized scheduler created as part of SMPng, and SCHED_4BSD,
an SMP-adapted version of the original 4BSD scheduler. They have
quite different performance properties, with ULE providing strong
interactivity characteristics, and performing quite well in a
number of benchmarks, and 4BSD showing greater strength in IPC
intensive user space benchmarks, such as databases. One of these
schedulers must be the default for 5.3, and whichever one it is,
it requires careful measurement, analysis, and optimization before
the release in order to address its deficiencies.</td>
