Solaris and Linux system information.
Hey,
I have a program that takes more time on a solaris machine than on a linux machine. So I guess the best way to know whats going on is to compare the two systems ? CPU and Memory ? Is there any other parameter that I should look at ?
So on the
linux box I ran:
Quote:
1) cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 15
model : 2
model name : Intel(R) Xeon(TM) CPU 2.80GHz
stepping : 7
cpu MHz : 2786.202
cache size : 512 KB
processor : 1
vendor_id : GenuineIntel
cpu family : 15
model : 2
model name : Intel(R) Xeon(TM) CPU 2.80GHz
stepping : 7
cpu MHz : 2786.202
cache size : 512 KB
% cat /proc/meminfo
MemTotal: 4003500 kB
And on the
Solaris:
Quote:
$ psrinfo -v
Status of processor 0 as of: 01/07/08 17:10:57
Processor has been on-line since 11/15/07 03:46:00.
The sparcv9 processor operates at 900 MHz,
and has a sparcv9 floating point processor.
Status of processor 2 as of: 01/07/08 17:10:57
Processor has been on-line since 11/15/07 03:45:59.
The sparcv9 processor operates at 900 MHz,
and has a sparcv9 floating point processor.
$ prtconf | grep Memory
Memory size: 4096 Megabytes
So I guess the fact that the CPU on linux box is
2.80GHz and on solaris box is
900 MHz made the difference ? lets assume that the system load on both the machines was the same.
What other commands can I use to get system information to diagnose these kind of problems.
Ive heard of intel processors but what is that sparcv9 processor on my solaris box? Is it only used on solaris machines ?
Also, on my linux box:
Quote:
$ uname --help
-m, --machine print the machine hardware name
-p, --processor print the processor type
-i, --hardware-platform print the hardware platform
$ uname -p
i686
$ uname -m
i686
$ uname -i
i386
Processor and Machine is i686, but hardware platform is i386. Whats the difference ?
Thanks in advance for any kind of input

linux-version
LINUX-VERSION(1) General Commands Manual LINUX-VERSION(1)
NAME
linux-version - operate on Linux kernel version strings
SYNOPSIS
linux-version compare VERSION1 OP VERSION2
linux-version sort [--reverse] [VERSION1 VERSION2 ...]
linux-version list [--paths]
DESCRIPTION
linux-version operates on Linux kernel version strings as reported by uname -r and used in file and directory names. These version strings
do not follow the same rules as Debian package version strings and should not be compared as such or as arbitrary strings.
compare VERSION1 OP VERSION2
Compare version strings, where OP is a binary operator. linux-version returns success (zero result) if the specified condition is
satisfied, and failure (nonzero result) otherwise. The valid operators are: lt le eq ne ge gt
sort [--reverse] [VERSION1 VERSION2 ...]
Sort the given version strings and print them in order from lowest to highest. If the --reverse option is used, print them in order
from highest to lowest.
If no version strings are given as arguments, the version strings will instead be read from standard input, one per line. They may
be suffixed by arbitrary text after a space, which will be included in the output. This means that, for example:
linux-version list --paths | linux-version sort --reverse
will list the installed versions and corresponding paths in order from highest to lowest version.
list [--paths]
List kernel versions installed in the customary location. If the --paths option, show the corresponding path for each version.
