Subject RE: Coyote/Http11 under load
Date Thu, 07 Nov 2002 21:30:43 GMT
The numbers were suspect because I was running 3.3 under
JBuilder but 4.0 externally, I'd imagine.  I set up clean
tomcat trees and ran them outside of any test environment
and I get these numbers:  (100 rqs/10 concurrent cx)

            TC 4.0.6       |     TC 3.3.2
        Http11   Http10    |    Http11    Http10
                           |
Rq/sec    26.9     25.89   |     18         27
kb/sec    393      377     |     266        404

Coyote/11 with Tomcat 3.3 is still a dog.  I would imagine
you'd get the similar numbers with any servlet as I changed
nothing but the servlet container between the tests.

I'm still investigating, but it may be easier for us to
move to 4.0.
