- <title>Timing Results</title>

- These timing results are from running the regression test with the commands

-% make all
-% time make runtest

- <para>
- Timing under Linux 2.0.27 seems to have a roughly 5% variation from run
- to run, presumably due to the scheduling vagaries of multitasking systems.

- <title>Version 6.5</title>
-
- <para>
- As has been the case for previous releases, timing between
- releases is not directly comparable since new regression tests
- have been added. In general, 6.5 is faster than previous
- releases.
