Calls of GetSize() from my implementation of AbstractListModel significantly decrease application performance.

Here is my code for getSize() method:

    @Override
    public int getSize() {
        return sessionRepository.getCountByPartnerOperatorCountPhoneFromTimeBeforeTime(
              selectedPartner, selectedOperator, fromTime, beforeTime, hideNullStatistic);
    }

Parameters in method call are filters, so when executing code in viewModel with implementation of AbstractListModel, this method is being called many times, every time executing a query to a db. Thus, with ~26000 rows in table, it takes about 10 min for a page to render.

Is there any way to overcome this problem (maybe make zk not to call getSize() so often or use different component)?
