Então algumas semanas atrás eu atualizei para 17.10 e praticamente ao mesmo tempo eu atualizei para o Android Studio 3, e foi provavelmente um erro atualizar tanto como agora eu não sei onde está o problema.
Basicamente, parece que o disco IO ficou muito ruim. No começo eu notei que estava trocando, então eu dobrei meu ram (32 shows agora) e nunca mais vou trocar. Mas a máquina ainda praticamente congela quando o disco IO acontece. Por congelamentos, quero dizer que vai ficar muito lento, ao ponto que eu posso digitar e não vou ver o que estou digitando por alguns segundos, muitas vezes eu vou pegar uma longa seqüência de uma tecla quando isso acontece.
Quando vou confirmar meu código, o Android Studio faz uma análise do código e a interface do usuário fica congelada enquanto isso é feito. Leva alguns segundos. Nenhum desses problemas costumava acontecer antes de atualizar as duas coisas.
Além disso, quando o backup da estação de nuvem é executado no meu NAS, fica ridiculamente lento.
Eu tenho um Samsung SSD 850 PRO 512GB
SSD.
Então, o que posso fazer para ver qual é o problema?
Obrigado.
