Почему WriteFile вызывает ReadFile и как мне этого избежать?
При последовательной перезаписи (например, 8192 байта выровненных и измеренных блоков) в существующих частях файла (иногда / всегда?)WriteFile вызывает чтение файла с диска, что полностью снижает производительность. Я не совсем понимаю, почему это происходит и как этого избежать.
С помощьюМонитор процесса Я получаю следующую информацию:

Следующая информация отCcCopyWriteEx может быть актуально:
Если Wait равен TRUE, CcCopyWriteEx гарантированно завершит запрос на копирование и вернет TRUE. Если требуемые страницы кэшированного файла уже находятся в памяти, данные будут скопированы немедленно, и блокировка не произойдет.Если какие-либо необходимые страницы не являются резидентными, вызывающий абонент будет переведен в состояние ожидания, пока все необходимые страницы не станут резидентными и данные не будут скопированы.
Если я правильно понимаю, это работает аналогично отображению в памяти, где перезаписываемые страницы должны сначала считываться с диска, даже если вся страница должна быть перезаписана. Есть ли способ избежать этого? Возможно, некоторыеРегулятор кеширования?
FILE_FLAG_WRITE_THROUGH имеет значение. Это все еще вызываетReadFile но не так часто, и объем чтения с диска, кажется, намного ниже. Хотя я не до конца понимаю, что происходит, а активность диска и длина очереди все ещенамного выше чем при записи на неинициализированные страницы в целевом файле.
