I have a search filter where it filter text from a table which is working good on firefox and chrome with no error.

When I try it on IE8 (which is our main browser) it works but the searching is very slow.

It like for like a second but I get no errors or anything like it.

Is there anything in my script that could possibly be making it slow on IE8?

I took out some of the table columns since I don't think showing them all makes a difference here:

 

....

    

      
Department
    

    

        
#dept_name# )
