Lenteurs de macros VBA sous Excel 2007 vs Excel 2003

**nicotab** · 03/08/2007, 14h10

Bonjour,

J'utilise une boucle "FOR" pour effectuer des traitements de remplissage dans un fichier d'environ 26000 lignes. Ce développement VBA programmé sous Excel 2003 prend environ 40 secondes. Sur le même PC sous Excel 2007, le même traitement prend 5 minutes.

Certaines fonctions sous VBA 2007 auraient elles changées au profit d'autres ?
Quelqun peut il m'éclairer svp ? Merci par avance.

Ci-dessous la boucle "FOR" en cause :
