Hi All,
A couple of questions which I hope are appropriate for this list:
1. Is there a document that details each VM instruction and the time it takes
in cycles on
a particular architecture?
I ask because often on the http://www.masm32.com/board/index.php forum they
provide
CPU c
Hi All,
I do believe getting the timings is possible.
>From working in x86 assembler I know that there are ways to get timings
from your own code, so finding out the timings for the bytecode execution
would require instrumenting the bytecode execution routines and carrying
out a test.
I'll loo

Hi All,
I'm wading through the openJDK source and I'm wondering, which file or
files are responsible for executing each bytecode ?
ie: the loop that gets a bytecode, works out what is it and then dispatches
it.

Hi All,
As promised here are two links to resources to help you time pieces of code
with a very high resolution.
Using this approach it is theoretically possible to determine the CPU cycles
each virtual machine instruction takes, thus enabling further optimization
at the bytecode level or in th
Re: Which file is the interpreter?
Thank you for the responses.
Gary Benson's blog is very interesting but also lengthy, and the
file templateTable_.cpp in src/cpu//vm/ looks close
to what I am after, but not it. Although I could be wrong given my
newness to the code.
Im looking for the loop t
Hi All,
I have a suggestion on a possible performance boost for the JVM which if I had

I would research more and implement, however, I'm rather time poor right now and
thought I could at least put the idea in the wild for someone else or myself at
a later
stage.

Hi John,
Thank you for the response.
Of course I see a lot of merit in what you are suggesting regards benchmarks and
the actual and more pressing concerns.
I do intend to work through a full and proper suite of tests and benchmarks to
show what if any improvement can be gained. However - in t
Hi All,
I'm wondering which bytecode generation library I should use for my SmalltalkJVM
project? What do you recommend?
Rgs, James.
