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 Smilie

psrinfo(1)						      General Commands Manual							psrinfo(1)

NAME
psrinfo, pinfo - Displays processor administration information SYNOPSIS
/usr/sbin/psrinfo -n /usr/sbin/psrinfo [-v] [processor...] /usr/sbin/psrinfo -s processor /usr/sbin/pinfo [-v] [processor...] OPTIONS
Displays the number of processors in the system. Enables verbose mode. Writes only a boolean value to standard output. The -s option requires a single processor identification number (processor). The -s option is intended to be used in scripts. A value of 1 is output if the specified processor is on line. A value of 0 is output if the specified processor is off line. DESCRIPTION
The psrinfo and pinfo commands display information about processors. The processor variable specifies the processor identification number, which is a unique integer that identifies the processor. If you do not specify any options or a processor identification number, the com- mands display information about all processors. EXAMPLES
The following is an example of the default prsinfo command output (no options or processor identification numbers): greene:> psrinfo 0 on-line since 11/03/1999 09:41:34 1 on-line since 11/03/1999 09:41:34 2 off-line since 11/03/1999 08:41:34 The following example shows how to use the psrinfo command with the -s option in a shell script to determine the state of the pro- cessor with an identification number of 1: if [ "`psrinfo -s 1 2> /dev/null`" -eq 1 ] then echo "processor 1 is up" else echo "processor 1 is down" fi The following example shows how to use the psrinfo command with the -v option: % psrinfo -v Status of processor 0 as of: 05/23/00 15:47:40 Processor has been on-line since 05/23/2000 15:08:04 The alpha EV5.6 (21164A) processor operates at 465 MHz, and has an alpha internal floating point processor. Status of processor 1 as of: 05/23/00 15:47:40 Processor has been on-line since 05/23/2000 15:08:04 The alpha EV5.6 (21164A) processor operates at 465 MHz, and has an alpha internal floating point processor. Status of processor 2 as of: 05/23/00 15:47:40 Processor has been off-line since 05/23/2000 15:08:04 The alpha EV5.6 (21164A) processor operates at 465 MHz, and has an alpha internal floating point processor. Status of processor 3 as of: 05/23/00 15:47:40 Processor has been on-line since 05/23/2000 15:14:00 The alpha EV5.6 (21164A) processor operates at 465 MHz, and has an alpha internal floating point processor.
