Server Performance Question

Sorry for posting this question here. It belongs in hardware I know, but I've posted there and they just cleanup spyware and deal with overclockning it seems. This is totally server based. And you sever gurus know hardware as well as the software i'm sure. So I apologize in advance.

My webserver seems to go slow. I want to do the most economical boost in performance.

I do a lot of server sided scripting. I host 5 sites, about 6000 pages, most dynamic with php scripting and mysql.
This is my entire setup.

3meg cable line (residential..I know) into a windows 2003 server. That server is my router/firewall/mysql server.
from there it goes to a cisco switch, which has my PCs and my webserver.
Win2k3 server is fairly good. 2.8GHz, 512mb, good enough for routing I'd say.
Plain cat5e for everything.
10/100mb nic in everything.

Webserver is a bit older.
Compaq Deskpro. 350mhz. 256mb ram. Pentium II I think. Original 6gb hard drive, single drive.
Webpages are slow to load, especially php ones. And if I try to browse my internal network it is fairly slow.
Linux, debian, apache, php. All command line.

So what would be the best upgrade? My network connection is obvious, but thats expensive for anything higher.

Would a better CPU orRam do it better? Or is it probably harddrive access, get a raid formation with atleast 7200rpm drives?

At work, large expensive servers, I can browse network shares like it's local folders. I would like something similar to that for the local network. And something to boost up my website loading times for external people as well.

Any suggestions? I can give lots more info.

if your low on money upgrade from 265mb to 512 or 1gb, stop all services you don't need, then check performance again

another option:
 switch hardware for router and web server, then move mysql to the web server machine too
 (256mb for routing and firewal is sufficient)

I was considering the switch. But then I'd have to reinstall both OS's. Windows 2k3 won't transfer over and I've never done it with linux so I probably will just reinstall.

I dont want to upgrade memory if it isn't needed.
What, with server-sided scripting, is the main resource hog? CPU, Memory, or HDD access time/data transfer. I was leaning towards hard drives because they are the slowest thing on a computer usually (except the user in most cases).

I guess that you php is the main problem. Did you enshure that it is mod_php and not CGI?

i don't know that much about it. or what to ensure what is mod_php or cgi.

If you mean the modules I load in the apache httpd.conf file then I do have:
AddModule mod_php4.c

as a line.

Also:
LoadModule php4_module        libexec/libphp4.so


The only references to CGI is:

<Directory />^M
    Options FollowSymLinks +ExecCGI^M
    AllowOverride None^M
</Directory>^M

    ScriptAlias /cgi-bin/ "/var/backhand/cgi-bin/"

    <Directory "/var/backhand/cgi-bin">^M
        AllowOverride None^M
        Options None^M
        Order allow,deny^M
        Allow from all^M
    </Directory>^


AddHandler cgi-script .cgi .pl


AddModule mod_cgi.c

Are these CGI calls in my httpd.conf file making PHP files load slower?

Which are safe to delete if so?

ahoffmannCommented:
I meant if your .php pages are called as CGI, doesn't look like according your posted config
You may use ps ax  to see if there're php running, that should not be when mod_php is in use.

Everything is located in /var/backhand in regards to webpages.
Bin has the httpd file and apachetc1 file.
Htdocs has webpages
Conf has configs.

nothing suspicious, what exactly is your problem (except PHP)?

undy30Author Commented:
I thought this was clear but it's more hardware.

What is the major thing needed for a fast websever, doing mainly php serving.

cpu
memory
fast hard drive
raid

or anything else. network can't be upgraded because it's much too expensive.

ahoffmannCommented:
cpu+memory

undy30Author Commented:
I really thought hard drive would make a large difference. Since I have a windows 2003 file server with a good cpu and lots of memory but browsing a network or serving files takes a very long time as well.

And the top command showed the cpu/memory were less than 1%.
But you're the expert.

sorry, not an expert for that, useless attempt ...

with cpu+memory I meant the linux one 'cause Linux caches as much as possible in memory (you don't need to configure that;-)

undy30Author Commented:
Really?
Interesting, I never knew that.
Maybe I'll save up for a gig of ram and a P4 2.8Ghz CPU instead of the fast SCSI drives then huh?
Should be enough for an entry level webserver.
Probably will get a new hard drive, just a basic IDE 7200RPM, raided for redundancy. Since the drive I'm using now, 24x7 operation, is about 10 years old.

Thanks alot for the info.
