<title>Timing Results</title>
<para>
These timing results are from running the regression test with the commands
<programlisting>
% cd src/test/regress
% make all
% time make runtest
</programlisting>
</para>
<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.

For the <systemitem class="osname">Linux</systemitem> system above, using <acronym>UW-SCSI</acronym> disks rather than (older) <acronym>IDE</acronym>
disks leads to a 50% improvement in speed on the regression test.

<title>Version 6.4beta</title>
<para>
The times for this release are not directly comparable to those for previous releases
since some additional regression tests have been included.
In general, however, 6.4 should be slightly faster than the previous release (thanks, Bruce!).

<title>Version 6.3</title>
<para>
The times for this release are not directly comparable to those for previous releases
since some additional regression tests have been included and some obsolete tests involving
time travel have been removed.
In general, however, 6.3 is substantially faster than previous releases (thanks, Bruce!).
