Dabo and Snow Leopard (OSX 10.6)

[Aaron Carlow]

I've been doing various testing an the three main platforms (windows, osx,
linux) and noticed that my Snow Leopard OSX 10.6 tests seemed slow compared
to the other platforms.  I have a table with about 100 rows and as many
columns and when I create a dGrid with all the columns and rows it feels
very sluggish.  The interesting thing is I see a process called "fontd" that
jumps to the top of CPU utilization list when scrolling up and down.  After
doing a little research on what "fontd" is it appears to be a replacement in
OSX for ATSserver:

fontd(8)                  BSD System Manager's Manual                 fontd(8)
*NAME*
     *fontd* -- Mac OS X system font registration manager
*SYNOPSIS*
     *fontd*
*DESCRIPTION*
     *fontd* is a system daemon which makes fonts available to the system.

     There are no configuration options to *fontd*.  Users should not
run *fontd* manually.
*SEE* *ALSO*
     atsutil(8)
<http://developer.apple.com/mac/library/DOCUMENTATION/Darwin/Reference/ManPages/man8/atsutil.8.html#//apple_ref/doc/man/8/atsutil>
*HISTORY*
     The *fontd* daemon first appeared in MacOS X 10.6 replacing the
ATSServer daemon.

Mac OS                          August 18, 2009                         Mac OS

I still had access to a couple Leopard installs (10.5) and decided to do the
same test and performance was significantly better, even with a table of say
8 columns. I have a feeling this may be a wxpython/wxwidgets issue and not a
dabo one but thought I'd bring it to the list's attention. Any thoughts?

I meant to say 1) that even with 8 columns 10.6 is slow and 2) 10.5 doesn't
suffer the same performance issue.  and 3) I need to proofread better :-)
