Improve Actual System for library pivottable.js to manage big amount of table

With Library [login to view URL] i need to improve a pivot table. u go to the site attached here, log, and go in left menu to pivot. There if u see, is a lot of data, and we needed to add year (año) and month (month), becuase without that as its config, cames with memory problems. Also can't handle more than 200.000 data to load fast. And original project can. Sure is a problem of config, i need to handle big data there fast, with no problem.
