When i said “run and the first instruction in “main”

it’s because i did your test
Sub Main(Client, GWEvent)
msgbox “Main()”
End Sub

Whith few forms, perhaps, with many and a big one (270Ko) it’s near 7 sec
Amount of RAM 2Go with XP for my workstation

Between “Run” and “Main”, what’s Formativ doing ?
Read Cache and load in memory ?
I search a clue to tunning the parameters

Thanks for help
