This is my first question here so please don’t be tough on me… 😛
I usually tend to google my way to a solution but now I’m in a hurry and have used up all the resources I had…
because my website is a commercial one, it would be fair to go ahead and pay someone to help me but… I have some financial problems myself, this was the 3rd month of payment to my dedicated server, still it was only the first month since my site was actually up… I have made it all by myself because I cannot afford paying anyone, and have no ads on it because I don’t think I would be getting anything now and the ads would just be useless…although I intend in using ads later in my site’s life, i don’t get a dime from the (at least for my budget) expensive server rent… 🙁
This is my problem:
I have a dedicated server which has been going great until a few days ago when my traffic started going up…for a few days, i keep getting emails from my cpu status monitor from my server…
it’s like stuck at full throttle and I’m trying to find out why and repair the problem!…
I’m really desperate so please help me!
here are my latest stats (though they’ve been like this for like 4 days…)
08:02:35 up 12 days, 14:39, 0 users, load average: 25.82, 25.98, 25.92
I use stat counter, I think they are pretty accurate (the code is on every page so these are my website’s global results)…
My stats are:
Page Loads Unique Visits
10,367 1,843
My main pages are index.php and videos.php (i run a video site btw)
the index and videos.php pages are always using around 140-150-160% of the cpu
i mean huh?
they’re using more than 100%? like loaning or what?
what they both do is:
(mainly the videos page, the index is just a simplified version of it)
check -and take if passed- a query and a page number.
query a database, take results from a table and show them
I use mysql_connect for everything i take from mysql.
I heard of permanent connections in mysql as being a possible solution to a large number of queries, but also read about a lot of cons to this method caused by security issues…
please advise?
my database is myisam engined
I have 2 main tables: games and videos.
Along them are around 5-6000 tables used for storing comments…
games table: 9 columns
id - primary
name - fulltext - used by my search
videos table: 17 columns
indexes:
id-primary
title,tags-fulltext-used by search
the rest of the tables are used for comments but they dont have any index except the id field.
they only keep the comment and the date in themselves.
when i load a search page, all data is taken from the db:
search for keywords, take the most relative and then echo all data related to the matched items.
when opening a video page, all comments from a certain db are loaded and displayed in a box.
what is the best thing I can do to reduce processing power use?
also, my support team just emailed me:
we have increased the table-cache to 12000 , please check now how it goes .And also it is better to get a my.cnf file which is most suitable to your working environment , here the mysql variables are set to the default values .
I just read something about the my.cnf file on google but nothing related to my case…
Could someone please indicate me what should my my.cnf file contain? related to my sittuation?
I have my server information here, but it takes some space… how can I close it somehow and you only open if you want to read? without using links?
should i just post it here like this?
Please, if a moderator reads this and can collapse it somehow, please do so!

I think this is all the information I have.
If you have mercy on me, please help!…
thanks a million billion times!hot
No, the load is expressed as one unit per CPU, so if your server has four CPUs, a load of 1.00 (or 100%) means that one CPU is at full load and the other three are idling (or two are at 50% load and the other two at 0%, or any similar combination) and a load of 4.00 (or 400%) would mean that all the CPUs are at full capacity.
Why should it be a security issue? Maybe it can be a performance issue if misused, but definitely not a security issue.
From what you’re writing it seems you’re quite a novice on relational database and perhaps web development, the first step I suggest is to buy a database book and learn how they work and how to use them, then a good book on PHP. Otherwise, you will be programming by coincidence and will never resolve your issues.
By the way, if you’re new (and you know it) you should give a read to the FAQs, How to ask and Editing help.
