Why the system shows incorrect CPU speed in Win2K
If you run Msinfo32.exe on a computer that has an Intel Pentium 4 Xeon 2.2-GHz or
faster processor, a very high processor speed may be shown. The Processor
information on the System Summary page shows the correct name, family, model and
stepping for the processor, but the approximate speed may be 37,000 MHz or faster.
This is because the speed of the newest Pentium processors exposes a limitation in the
speed calculation code in Msinfo32.exe.
To resolve this problem, refer to the hotfix described in the Microsoft Knowledge
Base article:
"Q302857
WMI Win32_Group ASSOCIATORS Queries Are Not
Optimized".
How to improve system performance for RedHat 7.2 and
RedHat 7.3
It is recommended to upgrade RedHat 7.2 to version 7.3, since there are many
improvements as well as kernel upgrade. Currently there is limitation about
multi-processor handling irq in RedHat 7.3. It is suggested to download the latest
kernel in order to improve the performance. The latest kernel 2.4.18 need patch to fix
multi-processor handle irq limitation. Please use the following steps to build the
kernel.
Download the latest kernel from http://www.kernel.org, for example:
linux-2.4.18.tar.gz .
# mv linux-2.4.18.tar.gz /usr/src
# gunzip linux-2.4.18.tar.gz (unpack the kernel)
# tar xvf linux-2.4.18.tar (extract form kernel tar file)
# patch -p0 < irq.patch (update necessary patch)
# cd linux
# make mrproper
# make xconfig
# make dep
# make clean
# make bzImage
# cp /usr/src/linux/arch/i386/boot/bzImage /boot/vmlinuz-24188irqbal
# make modules
