How to find out how much resources some mod uses?

[Alan_SP]

I have many mods and very much like them all. And yes, I always look for some new cool mods. But, every mod needs some server resources. And sooner or later we all need to decide which mods need to go and which can stay indefinitely as being easy on server. Of course, some are "strategic", we don't want to part from them no matter what, but even with such mods it is good to know what is their impact on server.

So, is there some easy to apply advice how to find out load that certain mod imposes on server? How can we test server load caused by single mod?

I know that queries are huge problem, but how to find out if mod generates queries and how many of them?

Please, any help on this subject is welcome.

If you go into debug mode, then you can get a look at all the queries and the time for all your processes.

How can I go in debug mode? And will it affect live forum? I read somewhere that it's not intended for live site, but I can test it only on live site.

Why can you test it only on a live forum? I would do it on a test site if possible. Anyway, see one of these:

Turn on the debug mode

I want to test in real environment as I think I'll get better idea what mods really do to server load.

Thank you very much. I like the best this option:

PHP Code:

 $config['Misc']['debug'] = ($_SERVER['REMOTE_ADDR'] == 'xxx.xxx.xxx.xxx'); 


Just need to find out what my IP address is and set it up. After checking server load, I just comment it out in my config.php and that's it. Nice and clean.

Is there any advice how to discern what queries are from stock vB, and what are from mods?

Some I recognize as from some mods, but many are just too confusing. Is there some tricks to quickly know what made query?

Sorry, I just made figure of speech, I know how to find out my IP address. You can also just type in google (if you use it) "What is my IP address" and here it is. Similar like you just could input simple mathematics formulas and use it as calculator (things like 2+2, etc...).

I usually grab a line and do a search in the vbulletin files to see if I can find the query. Or, you can point to your directory that has copies of all your mods and search through all the files there (the product files) to try to find it.

So, there's no easy way, but well, at least I get some idea what makes queries. And with some luck I could try and find mods that cause.

Thank you again. :up:

Alan, a lot of this is just something you pick up through experience. Start looking at your query pages and get familiar with what is going on with your pages. Then, when you have problems, it is easier to spot the culprit.
