Decrease the sort mem too much [8196] make the performance much slower so I use
sort_mem = 16384
and leave effective cache to the same value , the result is quite better but I
should wait for tomorrow morning [official hour] to see the end result.

Yes , I use this figure.
If the result still poor , putting more ram "6-8Gb" [also putting more money
too] will solve the problem ?
