Subject[Csnd] More info on score sorting issue
I did some more tests.  The same score with
32000+ events takes about a second to sort
on my Linux VM, and about a minute to sort
with from the windows command line on the
same machine.

Now, the Linux version is:

Csound version 5.12 (double samples) Nov 20 2011

While the windows version was installed with:

Csound5.17-gnu-win32-d

from sourceforge.

The score (and orc) can be found here:

http://tobiah.org/climb

The .zip file contains both orc and sco.

I noticed that this particular score has
many significant decimal places in the
p2 field.

The machine is a recent Phenom II quad.

Thanks for any help!

I can confirm that 5.17.3  (as released) is taking as long as you said on OSX too.
With the very latest from GIT, it's good:

Elapsed time at end of score sort: real: 0.160s, CPU: 0.153s

Looks like we need to update our release packages.
