I installed staus.php onto the server I am using.  See the info I get from it below.  Why am I not getting the Basic Info? 

And now...what do I do with it?  I think the server folks have the MySQL settings...

Please advise.

I am using SMF 1.1.1

QuoteWhy am I not getting the Basic Info?
Most likely, your web host disallows use of the system(), exec() or shell_exec() command. To check this, take a look at the disable_functions setting on a phpinfo page (What is phpinfo.php?) .

Note that it's a good idea to disable those functions ;)

Thanks....now if i can only figure out how to fix the indexing problems I am having and why some of these numbers are so whacked!!

Off the check phpinfo.php (that I know how to do).....OK back from checking.....there are no values in disable_functions

If you're having performance problems (or just want your forum to run faster), you'll want to go through the following steps to try to track them down:


  • If you're using SMF 1.0.x, make sure the "Check avatar size every time it's displayed" setting is off.  This setting was removed in 1.1.
  • Do you have eAccelerator or another optimizer installed?  What is eAccelerator?
  • Do you have a lot of posts?  If so, have you converted any of your tables to InnoDB?
  • Have MySQL's settings been tweaked to optimize memory usage and general efficiency?
  • If you're not on a dedicated server, are you sure others on your server aren't hurting your forum's performance?  If you're not ready for a dedicated server now, think about planning for one when your forum gets to a certain size.
  • Once you're satisfied of (or properly confused with) the above, if you're still having problems... simply create a new topic in this board, with the status.php file attached uploaded to your server, and some indication of peak times, what your problems are, and what you've done about them so far.

This is currently an incomplete list (although it contains the most important points.)  More detailed information is in the works.

-[Unknown]

Please read this thread before posting about performance issues

Well, I have tried all of the suggested things in the checklist and my forum is still slower than X-Mas.

I use fatcow for my host...all other sites I have on fatcow run fine, including a joomla! database I have on antoher site.

The forum is located here:  http://setformation.com/forum [nofollow]
Here's my server status file:  http://setformation.com/status.php [nofollow]
Phpinfo file is here:  http://setformation.com/phpinfo.php [nofollow]

PHP5. 

The slowness seems to come and go but is slow more often than not.

Please help!!!

Thanks,
Marty

Wait a minute!  I just read the Unix host post and changed the load.php script and truncated the sessions table and it seems to be better!

OK, nevermind.  It seemed to work well for a while, but is now slow again.  STILL NEED HELP!

I have posted a more detailed explanation on a seperate topic that is not stickied.

What's the 'Opened vs. Open tables:' mean? The value on my web host is 170.085 (which looks high, considering it says '(should be <= 80)'. Actually, what does all the MySQL stuff mean?

Haha, AMD can't spell. Supposedly, my web host has a "AMD Athlon(tm) Prosussor" :P

And this is mine:   Opened vs. Open tables: 38789.6719 (should be <= 80)
What does this really mean?

Also what does this mean: Have MySQL's settings been tweaked to optimize memory usage and general efficiency?

Something like that

It means MySQL is having to close tables to open others... and then those close those to open yet others. Your host should increase the MySQL table cache.

QuoteAlso what does this mean: Have MySQL's settings been tweaked to optimize memory usage and general efficiency?

Obviously they haven't here...

Thank You. I have put in a request to my host. hopefully they'll do it.

Darkness_, please don't post multiple items in different topics. It makes it harder to provide proper support.

 I am experiencing massive lag, as well, on my forum. The site has only a few users (@40), and though they are prolific posters, there is not enough traffic to cause load times to slow to as much as 2 minutes per page.

I suspect the simple fact is that the database is about maxed out - do you have any suggestions about shaving the majority off to archive, whilst keeping the current active thread content accessible?

I am not knowledgeable enough (yet) to determine if any of the internal settings need to be tweaked...but here is a copy of the status.php results, if it helps provide any clues...

Are you on shared hosting? If so, the server you are on is very overloaded.

Quote
Load averages:    8.48, 9.28, 10.04

Although you can still run things at that high of a load, it will bring slowdowns. Also, this "search.cgi" process seems to be taking up a lot of resources, at least as of the time you looked. Keep an eye on the load and if it stays high, contact the hosting company. If they refuse to listen, you might just need to look for hosting elsewhere.

 Hosted at GoDaddy, and I am sure they are jamming their servers with every client site they can pack in. Despite multiple requests to resolve the overload issue over the years, this problems crops up every now and then.
I know the database is getting really large, which is why I asked about it, but I have very little database mechanical know-how, and thus am not comfortable with taking any steps to reduce it's size without someone holding my hand, essentially.
With regards to the actual hosting reality, the bottom line is that they want to pop me for about 2.5 times what I pay now for the service... a couple of hundred bucks a year to simply host a 40 member forum.. not realistic, at all.


So.. I am hoping making a few changes will resolve some of the lag...

I need someone to help me take a look at what is wrong with my forum as I've been told by my ISP that my forum has overloaded the server.

I am forced to put the forum under maintenance for 2 days now as once I've set it online, the problem occur. My ISP has given me the warning that if such problem repeat, they will suspend and isolate my account.

Checklist for performance problems

1. I can't find this in my avatar setting -"Check avatar size every time it's displayed"

2. As of my acknowledgment, I do you have eAccelerator or another optimizer installed.

3. Yes, I have a lot of posts and did not convert any of your tables to InnoDB

4. I've tweaked my MySQL by using SMF optimization function in admin CP. Correct me if i am wrong.
