Subject: Re: [PATCH 0/11] Per-bdi writeback flusher threads #4
Date: Mon, 25 May 2009 16:57:22 +0100	[thread overview]
Message-ID: <4A1ABFE2.9050809@rsk.demon.co.uk> (raw)
In-Reply-To: <1242649192-16263-1-git-send-email-jens.axboe@oracle.com>

Hi Jens,

I've been testing this from your git version which builds as
2.6.30-rc6-00057-g81eabcf.

Unfortunately it's not doing too well.

When building a kernel with 'make -j 8' on my AMDX2 64bit, the screen
repeatedly locked up for several minutes at a time,and my music player
also froze.
In total the full kernel build took over 80 minutes, normally it's only
about 15.

However the machine seems to have recovered correctly, & now everything
is back to normal.

Maybe it does need the congestion handling after all?

regards
Richard
