I have a challenge to pose! :) There is new code in sword/tests/swbuftest.cpp that performs speed tests.
I bet you can't make it faster! :) (actually, I guess I bet you can or I wouldn't be posting this email)
SWBuf is our new replacement for the STL std::string class. It's used throughout our engine now, and where we were not allowed to expose STL in the API interfaces, now we can expose this class.
It is a very important class and it's methods are called 10's of millions of times during a typical run of a sword application.
This means any improvement in speed (even milliseconds) will be propagated in such a way as to make a big difference.
I'll perform the ratings on my system in single user mode so it's a fair contest. The current benchmarks are as follows:
[EMAIL PROTECTED] tests]$ time ./swbuftest > test.log
append ch test -------
append string test -------
subscript access test -------
constructor and assign test -------
compare test -------
real 0m18.378s user 0m16.030s sys 0m2.340s
Now, I would suggest saving the time and test.log file from a clean copy run on your system, so you have something for comparison. If a `diff test.log.orig test.log` produces anything, don't even think about submitting :)
The files involved should include:
sword/include/swbuf.h sword/src/utilfuns/swbuf.cpp
and for reference: sword/tests/swbuftest.cpp no changes to swbuftest.cpp, please.
And remember our API coding standards for cross-platform compatibility and leave the assembly code out :)
Have fun!
-Troy.
