Important Whoisonline makes site run slow and consumes large quantity of PHP memory

Hi Matias

I am attaching the screenshot of all the modules and plugin enabled on site. It would be a great help if you could have look on that and give me a idea which plugin are useless so I could disable that.
I have a backup on my local system and its running properly. On my local sytem I never got any error.

Hi sozzled

I have attached the screen shot of all installed extension, modules, plugin. Now could you have look on that and help me out in finding the reason behind it.

I looked. I was over-whelmed! :huh: I really don't know where to begin if you insist on keeping all those plugins. I don't know what half of those things do and most of those extensions are non-standard extra things that you've installed yourself. If you want me to diagnose your website for you, I can do that ... for a price. Please PM me with your requirements and I will advise you of my current hourly rate to investigate and advise you what to do next. Please note, I make no guarantees that I will be able to solve your problem but that still does not mean I will do this work for free.

Perhaps someone else, with some spare time, may be able to offer you their services for free and, particularly, if they have experience with the software cocktail that you have concocted. I just don't have three hours (or more) spare.

Hi Matias & sozzled
I finally found the memory eater plug in and its who is on line plug in of kunena itself. As I said before kunena installation my site was running smoothly with 64 Mb and its give me a clue so I started diagnosing with kunena and found who is on line plug in faulty. With who is on line plug in installed page is taking 10.235 second to load as shown by kunena at the bottom of the page and without it, it is taking only 0.23 second.

Interesting find. This is because of Kunena has been installed to sites with hundreds of thousands of users -- and is working just fine. There must be a bug in some environments that cause this issue, now we just need to find out what's triggering this issue.
