Not explicitly in the web application field, but I have a reference to a
very interesting study done at a German university to compare relative
efficiency between a number of programming languages; Java, Perl and
Python included. A string filtering application was used as the basis
for comparison, and a number of different metrics were taken.
I won't attempt to summarise here - have a look for yourself:
How does this relate to web applications? Well, the string filtering
application is a sufficiently generic one to allow at least an
indication of the relative performance of languages in web development.
- I would imagine that the 'typical' web application is far more
IO-bound than the string processing task. Or at least it should be!
Hence it is likely that the database structure is more important to
optimise than the language used to access the database.
- Sun's web development frameworks are far more advanced than those for
perl and python. Yes I am including Zope (albiet version 1.x) in this
generalisation. The EJB framework seems more scalable (at least in terms
of ability to add use cases) than any other web framework I have seen.
Admittedly it has been a while since I've done any web stuff.
