    Don't know what "cygwin" you are talking about, but the one  I
download from cygwin.com  seems to have several utils that deal with
ext2/ext3.  If  ext2/ext3 performance relative to NTFS is a verboten
discussion and has nothing to do with Cygwin, then perhaps
these utils shouldn't be in Cygwin??

------------------
The discussion has been about NTFS and how NT-native apps handle
fragmentation compared to Cygwin.

Cygwin's performance with NTFS (both default and optimized) was being
compared to linux's allocation performance on "xfs" and "ext2(&3)".

Two responses clarifying the test conditions on ext2/3 were asked and
then you declare the whole "discussion"[sic] as having nothing to do
with Cygwin?  Perhaps not caring for the topic, you haven't been
reading it?   The discussion has everything to do with the performance
on NTFS, the underlying filesystem that cygwin recommends vs. ext2/ext3. 

As for your assertion that ext2/ext3 have nothing to do with cygwin,
the cygwin distribution contains/provides several utilities ( as
shown above) for for creating, checking, debugging, resizing,
tuning imaging, labeling and dumping ext2/ext3 file systems.

The data I processed was output from "debugfs" -- a utility that also
exists on cygwin.

How can we begin to determine how well or poorly cygwin on top of NT
does if we aren't allowed to discuss how well ext2/ext3 perform.
For whatever reasons, they are the only non-NT file systems
cygwin seems to have utilities for.
