How do you want to benchmark it? It's not that easy. As a case study - I
moved one of my projects from mod-perl to JSDK. The performance
increased very drastically. Why?
1. I would need about 600MBs of memory in my server, while now 128MB is
more than sufficient.
2. I can integrate web applications with external apps in a single
process which gives me a lot of features and I don't have to use
frequent resource checks - I can use better mechanisms like
notifications and direct modifications of internal data.
3. I can share a lot of useful data between concurrent and successive
requests.
4. Becouse of (3) I was able to reduce database load 3 times.
Then - how can you compare which language is faster? Some problems
implemented in Java gave me 4000% better performance than in Perl due to
availability of better data model, better structures, strictier typing,
etc.
So, again - what is the correct meaning of database vs non-database
tasks? I mean - in terms of benchmarks.
