Pierwszy raz próbuję zrobić z tego głowy i ogony. Zastanawiam się tylko, czy dysk jest zły na tym serwerze? Po prostu kompilowanie i uruchamianie prostych zadań wydaje się być takie powolne (rzeczy się zawieszają). Podobnie jak średnia obciążenia idzie tak wysoko (8,00), a% WA jest również bardzo wysoki, by czasem nic nie działało.

Po prostu tego nie rozumiem. Kompiluję teraz, ale nic nie pokazuje się na górze, ale osiągam maksymalne WA%, a proces kompilacji jest jak siedzenie tutaj i nic nie robić, a potem po pewnym czasie znów się podnosi. /zmieszany
