Re: [PATCH] 2.4.20-rmap15a

Quothe Sean Neakums [off-list ref], on Tue, Dec 03, 2002:

Dave Barry, another
lnx-bbc developer, has observed something similar.  The difference in
system times seems to be above noise, too.  Both of the kernels I used
also had Stephen Tweedie's ext3 updates for 2.4.20 applied[0].  I can
retest without, if you wish.  I believe Dave's kernels had only rmap
applied, however.

	This is correct, and believe it or not i'm even using
	2.4.19 + rmap15a, no other patches.  I don't have my hard
	numbers available, but the difference between builds was quite
	significant, something like:

	2.4.19 vanilla:
	real 85m

	2.4.19-rmap15a:
	real 102m

I used ccache with these builds and they are almost entirely cached
(the big exception being gcc), so the job becomes fairly I/O-bound as
a result.  The builds are quite big: the CVS tree unpacks and builds
about three hundred megabytes of source, resulting in a build
footprint of approximately 2.9GiB.  

	This applies to me as well.

The volume I used for the build is
formatted as ext3, with htree activated.  

	My build volume is formatted ext3, no htree.
