HOw to increase the performance of filter for large set of data .???
The existing filtering code is already optimized, there is no way to significently increase it.
- fitlerBy functionality is few times faster than manual filtering ( same for #text_filter, #select_filter etc. )
- grid in SRND mode filters much faster than default one
- usage of #stat_* with filtering may decrease performance ( after each filtering stat need to be recalculated )
- grid in split mode is about 2 times slower than in default mode, this related to filtering as well.
In common case, it may have sense to use server side filtering , if client side filtering is too slow in your case.
