I actually reckon it's an anomaly down to my rather unscientific  
testing with wget. Using Apache's ab I get the following results for  
100 requests with 10 concurrent:

Using a PythonScript:

requests)

  100%    813 (longest request)


Using a BrowserView:

   50%    229
   66%    259
   75%    281
   80%    294
   90%    318
   95%    363
   98%    378
   99%    386
  100%    386 (longest request)

These figures tally in with the Profiler's results although I'm not  
quite sure where the difference in document length comes from.

Thanks very much for the tip.
