Im working at a small publishing outfit, and we've been pumping out 80
million hits a month for www.maximmag.com, from a 266MHz IIS/ASP box.
Weve just moved onto a 3-way clustering server, and expect to be able
to take pretty much anything that can happen. From time to time, our
site get mentioned on TV or by Howard Stern and it goes berserk, but we
expect to be able to handle that too.
All of our software is written by people without much regard for
performance or optimisation (e.g. stupidly complex SQL queries feature
in almost every page).
Ive considered writing caching software within ASP, which would cache
the semi-dynamic parts of the website (almost all of it), but its looks
like as long as our populaity grows at something less than Moore's law,
we can pretty much solve any problems by throwing more or better
hardware at it.
Ive looked long and hard at Zope and pretty much ANY Python oriented
solution which might be of assitance, but apart from my personal
predeliction for Python, there doesnt seem to be role for it in a site
serving these kinds of loads.
Now, my predeliction for Python is extremely strong; I loathe VBscript,
and the few opportunities to program in Python I get are like holidays
for me. If anyone can suggest a role for Python in a prodcution site
serving 80 million hits a month (and growing fast), I would greatly
appreciate hearing from them.
Ive only tried Python within an obscure branch of WSH called SSH,
without success. I havent tried it as a scripting langauge replacement
for VBscript, but there has to be a significant advantage to re-
educating all the vbscript people I work with. For the work they do,
VBscript is functional and they never seem to complain about it
Sometime soon, this company will be developing a unix capability,
either linux or solaris. I see this as some kind of opportunity to
introduce Python programming. JPython for (prototyping?) servlets under
one of the servlet engines looks appealing. Has anyone tried extremely
high volume serving using JPython servlets?
