Database interaction is by far the major issue. In my application, a page
with no db interaction runs in something like 80ms, while a page with DB
interaction takes something like 350-400ms. There's no silver bullet to
tuning tomcat applications, and most of the advice you'll get here won't
make any difference (use this connector, instead of that). So, my advice is:
Indeed some pages of my web application will cause more than 4-5 select
statement over tables with more than 50,000 records.
will a dual processor server handle this loads ? I used derby as database .
1) Using JDK 1.5. It can be up to 25% faster than 1.4
2) Use the server JVM
3) Allocate sufficient memory
4) Start tuning your application. Look at query execution times, and
the number of DB Interactions per page. Reduce the number of interactions by
using Stored procedure, or views.
How i can tune the database code ?
i just once worked with db2 , it has some facilities that bring up a
plan (execution path and detailed information about each step) of
statement and allow user to tune the database operations base on its
step and time that each step consumed , now how i can find such
facilities for derby ?
Thank you

Subject: Tuning Tomcat , i need some advice
Hi
Thank you for reading my post.
I have an application which will handle about 30 hit per second with
Tomcat 5.5.* (* wil be one of 15 or 12)
Now i need some advice about tuning tomcat to perform the best under
this condition
I read something so far , things like :
use Java server mode
increase the heap
Where i can find more reference and how to(s) or step by step
manual to
tune tomcat.
in condition that we have 30 hit/sec ,how much large connection pool
should be ?
is there some refrences about tuning connection pool?
Thank you
