Появление клавиатуры фризит recycleview

Есть несколько recycleview с разным количеством элементов загружаемых с сервера. так же есть searchview реализован getFilter. Проблема в том, что при наличии пары сотен элементов ничего не заметно. Если же больше 1000 то клик по searchview фризит все UI, далее появление клавиатуры, что продолжает фризить как и сворачивание её, такое ощущение что при смене фокуса происходит. Фризит ровно столько же по времени сколько и передача полученных данных с сервера в адаптер.

Код адаптера:

    private List<String> mDataNameParam;

// for filter
    private List<String> mDataNameParamFull;
