setTcpNoDelay(true) is not used in the TC 3.2.x, 3.3.
In TC 4.0 it's only present in http 1.1 connector.
Could you tell us more on Platform used in tests ?
Also could you send us code which was used to do the
benchmarks.
We may have here a different DEFAULT status depending
the OS running the JVM.
I'm VERY INTERESTED by this one, and I'll could add it
to TC 3.3/3.2....

Speak of the devil, I just ran across this page today, from a hosting
service:
http://www.aoindustries.com/servlet/com.aoindustries.website.WhatsNew
which says:
"Please note that AJP13 is still much slower than AJP12. Using AJP12,
ourstandard "Hello" servlet processes 544 requests per second. Using the
newer AJP13 protocol, that rate drops to a lowly 38 requests per
second."

This is on a RedHat 7.1 system, with Tomcat 3.2.2, Java 1.3.1 from Sun.
Sorry, I have no actual test code. Our web application typically creates
a frameset. Sometimes, four frames are reloaded as a result of an
operation. Anyway, when accessing the application via port 8080, it
responds fast, ie. all frames are drawn instantly. Accessing the
application via port 80 (apache-ajp13), it shows delays when those
same pages are accessed.
It's obvious, just by clicking around, that there's something
in Apache or ajp13 slowing it down.
Let me know if you have some benchmarking code I could run.

This is on a RedHat 7.1 system, with Tomcat 3.2.2, Java 1.3.1 from Sun.
Sorry, I have no actual test code. Our web application typically creates
a frameset. Sometimes, four frames are reloaded as a result of an
operation. Anyway, when accessing the application via port 8080, it
responds fast, ie. all frames are drawn instantly. Accessing the
application via port 80 (apache-ajp13), it shows delays when those
same pages are accessed.
It's obvious, just by clicking around, that there's something
in Apache or ajp13 slowing it down.
Let me know if you have some benchmarking code I could run.
