Timing Results

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

% cd src/test/regress
% make all
% time make runtest
    

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.

v6.5

As has been the case for previous releases, timing between releases is not directly comparable since new regression tests have been added. In general, v6.5 is faster than previous releases.

Timing with fsync() disabled:

  Time   System
  02:00  Dual Pentium Pro 180, 224MB, UW-SCSI, Linux 2.0.36, gcc 2.7.2.3 -O2 -m486
  04:38  Sparc Ultra 1 143MHz, 64MB, Solaris 2.6
     

Timing with fsync() enabled:

  Time   System
  04:21  Dual Pentium Pro 180, 224MB, UW-SCSI, Linux 2.0.36, gcc 2.7.2.3 -O2 -m486
     
For the linux system above, using UW-SCSI disks rather than (older) IDE disks leads to a 50% improvement in speed on the regression test.

v6.4beta

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, v6.4 should be slightly faster than the previous release (thanks, Bruce!).

  Time   System
  02:26  Dual Pentium Pro 180, 96MB, UW-SCSI, Linux 2.0.30, gcc 2.7.2.1 -O2 -m486

v6.3

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, v6.3 is substantially faster than previous releases (thanks, Bruce!).

  Time   System
  02:30  Dual Pentium Pro 180, 96MB, UW-SCSI, Linux 2.0.30, gcc 2.7.2.1 -O2 -m486
  04:12  Dual Pentium Pro 180, 96MB, EIDE, Linux 2.0.30, gcc 2.7.2.1 -O2 -m486

v6.1

  Time   System
  06:12  Pentium Pro 180, 32MB, EIDE, Linux 2.0.30, gcc 2.7.2 -O2 -m486
  12:06  P-100, 48MB, Linux 2.0.29, gcc
  39:58  Sparc IPC 32MB, Solaris 2.5, gcc 2.7.2.1 -O -g
