JQuery :: Slow Load Times Using .load()?

I have a page that contains 15 tabs. When each tab is pressed, it calls a function that uses .load() to load that tab. In my initial testing, all seems to go smoothly (loading in less than a second). However, once you click about 10 tabs, the pages start to load slower, and by click 13, it takes more than 30 seconds to load.If you refresh the page this process starts over and the outcome is the same (by click 12-13 it is unusable). Below is the code. FYI the reload_timer was an attempt to reload the page if the query was taking more than 10 seconds It didn't work. I left it in for feedback in case I don't find a suitable solution to the actual issue.
