You are in the wrong place. This is an idling forum.
Use it for mining then you will utilize every single bit of them
I wish there is some tweak I can put on Apache/MySQL / php to make them use all available resources.
Why would I buy a 8 core cpu if I Can't utilize it. There must be something I can do.
The idea behind having a powerful CPU isn't to force Apache/MySQL/PHP to constantly use max resources, but to give them room to grow, and room for burst usage when needed.
I don't know exactly what error you're getting but 'TCP_ERROR Operation Timed Out' seems to be more network related than CPU usage related, so might want to look into that.
It's the color. The graph itself and the frame and lattice must have different colors. Like blue graph on green frame and lattice.
"TCP Error Operation timed out" is a typical TCP Error with TCP standing for "Transfer Coloring Process" as you should know. Most probably your local client system can't deliver colors fast enough that's why you should use use different colors to use multiple cores of your CPU which also will give you higher CPU usage.
No offence man, but every noob thinks his web will be blazingly fast if he buys more cores and more ram. What you should do instead is: stick your head deep into system/webserver-logs and find where your bottleneck is!
I wonder, why do you use Windows Server to run XAMPP web server stack instead of Linux and a few software packages?
By default Xamp it's not optimized at all. Your going to need to tweak your Apache, PHP and MySql install manually.
Also using a windows server for a PHP app will definitely cost you on resources, have you considered IIS with PHP as fast_cgi or even better move to Linux based OS.
Yes. But in my case, they won't grow at all. There are a lot of room to grow. Yet they won't grow.
I am pretty sure it's not network. Network traffic is barely hitting 1Mbps.
I am not really hoping for blazingly fast. Just for my website load under 5s.
This is the reason I am asking. Any idea on how to find what bottleneck my website ? because CPU,RAM,Network,Disk all is far below the maximum capcity.
Because there are a lot of software that I used that only run, or run better in windows. Also because my PC is obviously using Windows. I can sync my works using Google Drive and One Drive, which can't be done or very troublesome to do in Linux, because of lack official software.
Is there any link / guide to tweak xampp ? to make it use all of the resources available ?
I am not considered that. The main reason is because it's portable.
Not an option.
"TCP Operation timed out" can have many reasons many of which can also be existing with low traffic.
Absolutely not. You are asking because you want OTHERS=US to find the answer that you are unwilling to find.
You threw a rather meaningless screenshot and an error message at us and did not even care to give us some context and data.
What are we supposed to do with
?? Are we supposed to look into a magical crystal ball? Because you gave us NOTHING to work with. All you told us boils down to "Help, my server doesn't work plus I want it to be faster".
Do not expect others to invest more in solving your problems than you are willing to invest in describing it properly.
i don't know what the real OP want to know, but the tittle says want to stress the cpu usage, so here it is:
install IntelBurnTest (http://m.majorgeeks.com/files/details/intelburntest.html). if some core is idle, run another instance.
but don't run it for more than 15 minutes ... don't even try. especially if you rent the server.
Any idea how can I describe it more properly ? What data do you need ?
My Website is a Wordpress (W3 Cache Enabled). It has about 400 Visitor. That visitor is filling forms, to be processed and saved into the database.
I am asking this because I absolutely have no idea where to start. If the CPU/RAM/DISK is 100%, I can start by looking which process use the most CPU/RAM/DISK and fix it accordingly. Right now, neither resource is at their maximum capacity. Hence the question.
Actually no, I don't want to test / benchmark my CPU by using tools.
I want to know if Apache / Mysql / PHP is capable of using my server maximum resources.
Sometimes apache is crashed, and I need to restart it, while in the other hand it still has a lot of resource available. Why apache choose to crash instead of using those idle core.
Is there any config that limit apache / php / mysql to use certain amount of resource ? and forbid it to go above and beyond ?
int main( int argc, char **argv ) { while( 1 ); return 0; }Save this as usecpu.c then
gcc -o usecpu usecpu.cand start one instance for every thread your system has. Mission accomplished.@yokowasis
You should seperate the two issues and first concentrate on the TCP timeout problem. Once that is solved you have a basis for optimization which your other question basically is.
A typical path to take with that kind of problems is to find out whether your server is reachable. ping and traceroute or mtr can help. Next you should be sure that your server stack is running. I don't know about windows but I strongly assume there is something like logs. Additionally you might want to check whether PHP is running properly e.g. by installing an ultra simple "hello world" script.
every network issue, began from:
Yes, I can even RDP
Not tried yet, will try when my website down again.
Ping is fine, I can even RDP with no problem. So I guess we can rule out network problem.
Server Stack is Running. I can visit localhost, but when I type domain it is very slow. If it's not timeout, it will take more than 30 sec just to load the front page.
to make it clear, my website works fine, if it has less visitor. All function work as it supposed to. But when the traffic (400 users) hit my server, my website load very slow, or timeout. With my dedicated server specs, I believe it can even handle 2000 concurrent user.
You may be a good candidate for managed hosting. Try knownhost.
My car doesn't work. I mean it won't levitate.
How come? Welp.
Any errors in the Apache error log?
The most entertaining threads on LET are when people come to ask for help but then insist on ignoring everyone's advice because they know better.
PHP string manipulation on windows is SLOW (we had a problem with this for one of our customers)
Most likely related to database - this would explain how CPU could be relatively idle while waiting for locks to be released. Without knowing any more details, that would be the first thing I'd take a closer look at. (Also, if I remember correctly a previous thread from some time ago, a more informed approach to database design in general was strongly suggested for this application.)
Wow, good memory: https://www.lowendtalk.com/discussion/132457/mysql-from-ram-drive-is-it-possible/p1
Apache max concurent reached?
How come?
You have a scaling problem, not a performance issue. Somehow your stack or code is really bad at scaling up to the resources available. Since you seem really new to all this I wouldn't know where to even begin to point you in the right direction... I guess, check out some performance guides for Apache, MySQL, PHP and Windows. There are thousands of things that might be going wrong and PHP/Wordpress is notorious for having bad performance.
Come on, man...he's using Apache, MySQL, and PHP. You can't run that on Linux.
I think because of this reason.
