Sorting VERY SLOW (8s) with only 11 rows

[pkkid]

Long (140 char) string values in a cell are causing tablesorter to be VERY slow. I have 11 rows in my table, and sorting is taking upwards of 8s. It seems the direction of sorting also has a large impact on performance as well. It gets gets worse with each row added and actually causes FF to popup the "Long Running Script" message, killing the page.

A JSFiddle example here (try sorting by Name):

With debug on, I am getting these messages:

Sorting on 0,0 and dir 0 time (2172ms) [VM] jquery.tablesorter.js (2583):111
Rebuilt table (1ms) [VM] jquery.tablesorter.js (2583):111
Completed applying 0 widgets (0ms)

Sorting on 0,1 and dir 1 time (8696ms) [VM] jquery.tablesorter.js (2583):111
Rebuilt table (1ms) [VM] jquery.tablesorter.js (2583):111

It should also be worth noting that I tried updating to the latest v2.10.8 codebase and am seeing the same problem.

Hmm, that is really slow. But I think it is slow because the data in all those cells is exactly the same and it's attempting to do it alphanumerically - which should be chunking the data, so it shouldn't be "that" slow. I'll have to dig into this more when I get back. For right now, I would recommend moving the "alpha"-part (MySnmp) into another column (demo)

I found the problem, I'll have it fixed in the next update.... basically I'm just going to remove the sorting of dates by the natural sorter since in tablesorter we use parsers to detect and convert dates into numbers.

Awesome. I appreciate you looking into this, and for the great app in the first place.
