Hi,
I supposed that compiled VB-code, in an ActiveX DLL, was working better than the same in ASP-code. Here is my code.
My ASP-Page
<body>
<%
if trim(len(request.form("f_Hit"))) > 0 then
'Calling my VB-DLL
response.write(time & "<br>")
Set cstring = server.createobject("Concat_String.String")
if request.form("f_hits") <> "" then
cstring.al_hits = request.form("f_hits")
end if
test = cstring.create_string
response.write(cstring.as_string)
end if
if trim(len(request.form("f_Hit_ASP"))) > 0 then
'With ASP
response.write(time & "<br>")
sstring = "string "
if trim (len(request.form("f_hits"))) > 0 then
for i = 1 to clng(request.form("f_hits"))
sstring = sstring & i & " * string"
next
end if
response.write(sstring)
end if
%>
My VB-DLL is the following
Option Explicit
Private ms_string As String
Private ml_hits As Long
Public Property Get as_string() As String
as_string = ms_string
End Property
Public Property Let al_hits(ByVal value As Long)
ml_hits = value
End Property
Public Sub create_string()
Dim i As Long
ms_string = "string "
For i = 1 To ml_hits
ms_string = ms_string & i & " * string "
Next
End Sub
--> As you see, the loop in ASP is the same as in VB.
When I'm running the two possibilities with 15000 hits,
the asp takes 46 seconds and the VB-DLL takes 56
seconds.
Can anyone explain me the reason?
Thanks

No surprise.
ASP is very fast indeed. What your Dll brings to your application is maintanibility, extensibility, scalability, security, plus you program in an N-tier model, and if you install your dll in MTS or COM+ you'll get connection pooling. Actually read this:

Have fun
