dll too slow as apartment thread

[lalonde]

my VB dll is too slow when compiled as an apartment threaded DLL (with unattended exec. + retained...).
The DLL is accessed in IIS (asp)

The dll basically creates a text file with everyhit to the site. (we use the scripting object and not the "#fileHandler". Unique file names are assured using the sessionID & another time variable...

However, when compiled as single thread, we have the performance we want but the server freezes as soon as two users "hit the site" simeltanously...

Any hints are appreciated,
Thanks

Without looking at your code here are some suggestions.

Are you creating unique names for every file?
Are you closing the files properly?

yep, file names are unique and the file is closed properly.

Another guess ,

Does the dll or the class some initization code ? In apartment threaded app this code may execute several times then in single thread.
