Okay, this has been driving me nuts. I have a machine setup as a
webserver/email server. I am using 4.2-RELEASE on the below described
machine. When I attempt to execute a PERL program, there is a long delay for
the compiler; it takes 25-30 seconds to print a simple 'Hello World" string.
Once the compiling seems done, the scripts actually run okay, but as most of
these scripts are for CGI apps, it really isn't going to do. The machine
should be MORE than fast enough to handle these little scripts. The uptime
command produces the following:
3:50PM up 14 days, 38 mins, 2 users, load averages: 0.00, 0.00, 0.00
Stating that the load isn't very high at all. If I watch things with the
systat command, PERL spikes right up to start a script takes like 98% of the
resources (same is true when I use top to watch what's going on), then
settles to what would be 'normal' once the app is compiled. While running an
app written in PERL, the speed seems fine.
I've been trying to compile a new kernel now for about an hour, and it
seems that compiling C takes a long time too. I have compiled the new kernel
with maxusers set to 256, and the CPU type set to i686, I don't know if it
will help or not. The system specs are as follows:
950mhz AMD Athlon CPU (slot not Socket)
128megs PC133 RAM (I know, clocks to 100 in this system)
Intel EtherExpress Pro 100 PCI
Promise ATA100 PCI Controller
Maxtor 7200RPM 60Gig ATA100 Disk, (4Gig root, 400meg swap, 55Gig /mail)
System also mounts all of the document storage (where the scripts are
located) over
NFS, (/server). I have tested running scripts from local filesystems to
prove that NFS isn't
the bottleneck.
If anyone has any ideas as to why the system seems to be doing so
poorly, please let me know. I had origionally installed the system with a
snapshot of the 4.2-STABLE branch, then most recently (about 15days ago or
so), went to 4.2-RELEASE because of the speed problems. The switch in
releases made no change to the problem; I am hoping the new kernel will fix
things, but figured I'd ask around anyhow.
