I'll try and explain the best I can, it's unfortunate I can't record my screen to show you what I mean. But i'll explain it anyway.

I installed the product and all was fine and seemed to be working well. Did a few tests sending PMs and stuff to see it work.

Then I was typing a reply to a thread and I was looking at my keyboard as i was typing it but then when I looked at the screen I noticed lots of errors in my typing which i thought was odd. Lots of letters appeared missing. Firstly I didn't link this issue to this product being installed and I put it down to maybe my PC was doing something in the background which was using quite a bit of CPU every few seconds. So all I did was restart my PC.

Then I went back on to my site and tried again, and I noticed the same thing happening again, but I kept missing it because IO wasn't looking at the screen when typing. So I decided to hold down the button F and see it happen, and every few seconds I would notice it stop and then continue. This is the bit where letters were missing. So I opened Notepad and did the same thing, held down the letter F and not once did it stop. This told me it was my website and not the computer.

The next step I took was to disable this product as that was the last change I made to the site, and I removed {vb:raw livenotifications_header} from the header template. Refreshed my site and tested typing a message. Not once did it stop when i was typing. Then to test it further I enabled the product and added the line back in to the header template, refreshed my site and did another test, and it kept stopping every few seconds. So I did the test again and I have copied the results from both tests so you can see what issue i'm facing.

This sentence was typed when the product was disabled and the code removed from the header template:


This sentence was typed when the product was enabled with the code in the header template:


As you can see the errors are evenly spread out throught the sentence which indicates the issue happens every few seconds.

For me this has confirmed that this product is the cause of this lag, however why it is causing it is unknown.

So for now disabled and marked as uninstalled.

Hey mate, this issue is easily fixed by turning up the Ajax Interval:



Basically, you are pinging your database more than your server can handle. Setting this to 30seconds or even 45 seconds will remove this issue on your site.
