Slow website after some time (with ajax interval of 10 seconds)

[dlegendkiller]

Hi. I have created a Hotel Management System which is loaded with scripts especially ajax.

The main interface comprises of checked in guests which is being updated/refreshed every 10 seconds.

The reason for that is to inform the user (cashier) that a guest's stay is over.

The problem is, when I have 80 or more rows (checkin), the system slows down. It's consuming a lot of memory.

My resolution was to upgrade the RAM to 6GB and increase the cache size of google chrome to 200MB.

Unfortunately, the problem still exists.

I appreciate your help and time. Thank you.

PS I attached an image of the user interface.

do you have an AJAX request for each row? or do you get all the updated data in one request?

Hi Dormilich. Thanks for spending your time helping me with this.

The function contains a lot of ajax requests but the data is not requested per row.

Here's the code for your reference. THanks.

The function starts from Line 9 to 158.

the problem I see is line #76. each time the getContents() function runs, you add another click handler.
