Application VB6 sur Vista tournant lentement avec beaucoup de "FAST IO DISALLOWED"

Question

J'ai un client qui exécute une application VB 6 personnalisée qu'ils ont écrit sur Vista. L'application s'installe et fonctionne bien sur Vista. Cependant, sur un PC Vista, l'applcation se charge et fonctionne très lentement. J'ai eu IT exécuter une trace de moniteur de processus et je vois une tonne de "FAST IO DISALLOWED" résultats ainsi que d'autres problèmes. Qu'est-ce qui peut causer "FAST IO DISALLOWED" et comment puis-je le réparer? Voir ci-dessous trace partielle:

Mise à jour: Il semble que les charges applcation ok, mais tourne lentement lors de l'ouverture des rapports, etc.

Mise à jour: J'ai un froma trace PC qui fonctionne bien. Cependant, je crois que la lenteur est parce qu'ils ont laissé ODBC traçage sur. Il y a une tonne de ces derniers:

Answer 1

Ils avaient laissé le suivi ODBC activé et c'était la cause de la lenteur. La désactivation du suivi ODBC l'a corrigé. Merci à tous.

Answer 2

Avez-vous l'exécutez le même moniteur sur la machine de travail comme un test de contrôle?

Je pense que vous trouverez peut-être que les défaillances rapides IO sont normaux (l'API est conçu pour tenter rapide IO d'abord, puis à plus fallback approche traditionl en cas d'échec). Dans les deux cas, il s'agira d'un problème de configuration de la machine (comme un problème de pilote) plutôt que d'un problème de programmation.
