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.
One more thing, one solution was to restart the computer and it comes back to normal. However, after some time, it will come back. The system is running 24/7 and being restarted every 12 hours.
Here's an image of the user interface. http://s12.postimg.org/qoc6t75q5/Capture.png
