I have a web site on a shared RaQ4 server.
It is often slow.
I'm just learning how to use PuTTY to monitor the
server.
For example right now the server is slow, and PuTTY
shows
12:09pm up 1 day, 16:52, 2 users, load average: 3.40, 3.15, 2.81
123 processes: 115 sleeping, 8 running, 0 zombie, 0 stopped
CPU states: 86.8% user, 13.1% system, 0.0% nice, 0.0% idle
Mem: 1048576K av, 605612K used, 442964K free, 0K shrd, 0K buff
Swap: 1048576K av, 0K used, 1048576K free 0K cached
Somewhere I learned that the server will perform well if the
three load averages are all below 2.50. In the example shown
above the load averages are 3.40, 3.15, 2.81 which makes
them all above 2.50.
I entered the command "top" into PuTTY and can see a list of the
server's users.
One USER has %CPU at 38.5, 72.8, 66.6, and similar numbers
that I can see as the screen refreshes every few seconds.
I have not seen less than 35% for this user. The COMMAND for
this user is often listed on PuTTY as "sendpasswd pl".
I created my site using Microsoft's FrontPage. Often when
I try to upload the site to the server, I get one of two error
messages: "can't parse ..." or "root busy ..."
Early this morning I started the upload operation, which
is called Publish in Frontpage, then went over to see what
PuTTY was showing. Sure enough my site was listed and
was using 5 to 8% of the %CPU.
Then the upload failed, an error message appeared in
FrontPage, and PuTTY began showing larger numbers for
%CPU, like 38 to 50%.
Remember I'm new to this, but I surmise that my error
message was causing the server some trouble, and the
higher %CPU reflected the work the server was doing,
as it tired to resolve the problem.
After quite a while, maybe 15 minutes, the problem on
the server was gone.
Now I'm wondering if the high %CPU numbers shown
above for that other other USER, like the 38.5, 72.8, 66.6 that
I mentioned above, are a result of the server thrashing
about looking for some password or something.
Please help me analyze this data.
Thanks,
Tom
