System Performance - Vmstat and Uptime
Hi all,
I have a supermicro system with Slackware 10.0 kernel 2.4.2 compiled with SMP
This system is SCSI and has 2 Xeon 2.4 processors.
I am experienced some slow performance and high Load Averages on it, but I can't detect exactly what is causing this.
I put more memory and this 2nd processor but the problem was not solved.
The load avarege consistently are over 10.0 to 18.0
This system run Exim 4 with MySQL, Spamassassin, Clamav, Pop, Smtp and Apache running a Perl Webmail.
The traffic in the system is about 3.0 Megabits and we have 6.000 mail users accounts in this server.
Below are the 3 uptimes and the VMSTAT of my system, if anyone can give a tip, I am very gracefully!

I have a supermicro system with Slackware 10.0 kernel 2.4.2 compiled with SMP
This system is SCSI and has 2 Xeon 2.4 processors.
I am experienced some slow performance and high Load Averages on it, but I can't detect exactly what is causing this.
I put more memory and this 2nd processor but the problem was not solved.
The load avarege consistently are over 10.0 to 18.0
This system run Exim 4 with MySQL, Spamassassin, Clamav, Pop, Smtp and Apache running a Perl Webmail.
The traffic in the system is about 3.0 Megabits and we have 6.000 mail users accounts in this server.
Below are the 3 uptimes and the VMSTAT of my system, if anyone can give a tip, I am very gracefully!
