WimMark I report for 2.5.64-mm1
Runs with anticipatory scheduler: 547.28 580.69
Runs with deadline scheduler: 1557.79 1360.52
WimMark I is a rough benchmark we have been running
here at Oracle against various kernels. Each run tests an OLTP
workload on the Oracle database with somewhat restrictive memory
conditions. This reduces in-memory buffering of data, allowing for
more I/O. The I/O is read and sync write, random and seek-laden.
The benchmark is called "WimMark I" because it has no
official standing and is only a relative benchmark useful for comparing
kernel changes. The benchmark is normalized an arbitrary kernel, which
scores 1000.0. All other numbers are relative to this.
The machine in question is a 4 way 700 MHz Xeon machine with 2GB
of RAM. CONFIG_HIGHMEM4GB is selected. The disk accessed for data is a
10K RPM U2W SCSI of similar vintage. Unless mentioned, all runs are
on this machine (variation in hardware would indeed change the
benchmark).
