Hello,

I correct a typo, read again about capacity planning and queuing theory..

I have bought the following book called Performance by Design: Computer
Capacity Planning By Example here:

https://www.amazon.ca/Performance-Design-Computer-Capacity-Planning/dp/0130906735

And the book is analyzing the performance of an E-Business Service with
queuing theory, but i think its methodology is error-prone because it
contains many mathematical calculations, so this is why i have decided
to construct another methodology that is much less error-prone and that
is easier and that uses the Jackson network , so my methodology works
with 65% or more of database read transactions, the total of write and
delete database transactions must be 25% or less, and it works too when
it is 65% or above of database write database transactions, so i think
my methodology is suitable to do capacity planning with mathematical
queuing theory of E-Business Services, and i will write a book about it
and explains my methodology, and of course i am taking care of the http
or https overhead and i will provide you with a program too.

Read the rest of my previous thoughts:

More about discrete-event simulation (DES) and more..

I am not only a more serious software developer specialized in parallel
programming and synchronization algorithms, but i have also studied
operational research and i have studied more mathematics, so here is an
interesting Free simulation software for Delphi and Freepascal called
OpenSIMPLY:

And i have also implemented M/M/n queuing model simulation with Object
Pascal, here it is:

And i have also made my tutorial on how to solve Jackson network problem
with mathematical modeling, you can download it from my website:

I have also implemented Maxflow algorithm for Delphi and FreePascal,
here it is:

Thank you,
