Subject: Performance 2.2.13 and USB work
Date: Wed, 01 Mar 2000 10:37:51 +0100 [thread overview]
Message-ID: <38BCE4EF.85135592@inu.se> (raw)
In-Reply-To: 20000229054521.6C2385064E@brixi.research.canon.com.au
We've been using 2.2.5 and wanted to move up to 2.2.13
So, we made a diff on all changes we've done on Malek's 2.2.5 and
applied that to 2.2.13.
We then ran a test on it and found 2.2.13 was 3 times slower than 2.2.5!
We haven't analyzed what made the difference (or in fact what changes
we've introduced to 2.2.13 with the patch, other than the reported
conflicts).
Is there anyone that experienced the same fenomena?
What might be the reason for this?
USB,
We've been working on an USB host controller interface for the MPC850
and now it works with the ACM driver. It doesn't support URB for now.
Cheers
Bjorn
