Parsing large data on firefox causes unresponsive script error to pop up. Any fixes availabe?
I found the issue. Since the data is large, its taking too much time in “_compute” to apply my math formula. This makes the script unresponsive in firefox. Any suggested fix for this??
Can you share a snippet or a demo link where problem can be reconstructed ?

If you open above webpage in firefox and scroll down to load some more data, firefox becomes unresponsive and throws unresponsive script error. If I remove “math” from column configuration, it works fine. Also it works fine in chrome.
Unfortunately there is no any errors in your code. That is raw performance problem.
Each time as you are using .parse command, DataTable will recalculate math for all rows, and this number will increase with each next .parse call
After third data loading DataTable contains about 200 000 cells, all of them need to be checked for possible math calculations.
By the way, call to refreshColumns will force full math recalculation as well
Also, about 30% of time is spent in summTreeColumn handler. This one is triggered after each data update in the DataTable.
As possible solution we can add an extra option that will prevent double processing of already parsed data ( only newly loaded rows will be math processed )
