angularjs - Angular Material Autocomplete is slow -

-

i have angular material autocomplete setup runs $http request when search text changes, php side takes ~1 second, request overall takes 3 seconds! it's autocomplete north american cities (only 2000 rows in table) it's not query time (0.0025 seconds in phpmyadmin - there's full text index on column being searched) i'm worried overhead angular adds. it's laggy , if load 2000 cities browser lags when type in autocomplete!

how can speed work normal autocomplete?
