Hello there !
I had been doing some experiments in one of our servers, it is using
apache - mod_jk - tomcat-3.3.1 over a Linux box.
To improve performance I decide to find out what could happened if I
increase the number of tomcat servers, so I have inside the same linux
box...
tomcat-3.3.1(1)
Apache -> mod_jk --<
tomcat-3.3.1(2)
I have been testing this new configuration and find out better
transaction rates...
For instance...
9,21 transactions/second to 11,74 t/s
Each test I done outperform old architecture in order of 20%...
Why? As I think, a dual tomcat configuration must be slower due to
double memory consumption, but figures show me opposite... �is this
normal? �may I increase the number of java threads, memory... for one
tomcat in order to get the old architecture works as fine as this
"strange" one?....
This is some data about my configuration...:
TOMCAT_OPTS="-Xms256m -Xmx512m"
<Http10Connector
port="8080"
backlog="1024"
secure="false"
maxThreads="150"
maxSpareThreads="5"
minSpareThreads="5" />
<Ajp12Connector
port="8007"
ajpidFile="conf/ajp12.id"
backlog="100"
secure="false"
maxThreads="25"
maxSpareThreads="5"
minSpareThreads="5"
pools="true" />
<Ajp13Connector
port="8009"
backlog="512"
secure="false"
maxThreads="150"
maxSpareThreads="75"
minSpareThreads="25"
pools="true" />
(The same configuration is used with both architectures).
Thanks in advance.
