Приложение VB6 на Vista, работающее медленнее с «FAST IO DISALLOWED»

Question

У меня есть клиент, на котором работает пользовательское приложение VB 6, которое они написали в Vista. Приложение устанавливает и отлично работает в Vista. Однако на одном ПК Vista ПК загружается и работает очень медленно. Я выполнил трассировку монитора процесса, и я вижу тонну результатов «FAST IO DISALLOWED», а также другие проблемы. Что может вызвать «FAST IO DISALLOWED» и как я могу это исправить? См частичный след ниже:

Update: Кажется, что applcation нагрузки нормально, но работает медленно при открытии отчетов и т.д.

Update: У меня есть след froma ПК, который работает нормально. Тем не менее, я считаю, что медленность заключается в том, что они оставили отслеживание ODBC. Там тонна из них:

Answer 1

Они оставили следы ODBC, и это стало причиной медлительности. Отключение отслеживания ODBC зафиксировано. Спасибо всем.

Answer 2

Вы имели IT запустить тот же монитор на работе аппарата в качестве контрольного теста?

Я думаю, вы можете обнаружить, что Fast IO-сбои нормальные (API предназначен для быстрого запуска IO, а затем возврата к более традиционному подходу при сбое). В любом случае это будет проблема конфигурации машины (например, проблема с драйвером), а не проблема программирования.

Answer 3

Попробуйте переустановить компоненты Runtime Microsoft VB6.
