All,
I have an .asp page that returns a jpeg image. It works
fine, and performs as expected, taking around 1.5 seconds
to authorise the user in a DB, open a web connection to
the internal image server and pass the image back to the
client. The image is requested as an ID number passed in
the QueryString
Until now, there has only been a single such image on any
given page and I've not noticed the problem. However, a
page that lists 20 or so thumbnails (6-7k each) takes
forever to load the images - roughly 3-4 seconds each -
and they always load sequentially.
It looks like there is an overhead to starting an .asp
page with a mixture of VB and Perl, and that something
is only allowing one such page to be interpreted at a
time... replacing the single page with, say, ten pages
and calling them round-robin style does not cause the
images to load any differently.
Watching the server activity, you can see individual
processing peaks for each image as the .asp page is
executed (they match nicely with the peaks for bytes-sent)
No doubt there is something somewhere in my code causing
this, but has anyone got enough knowledge of how the
perlscript bit of Active Perl works in conjuction with
IIS 4.0 to comment?
