Subject: [Qemu-devel] [PATCH 0/4] tcg memory usage improvements
Date: Thu, 23 Jun 2016 11:02:58 -0700 [thread overview]
Message-ID: <1466704982-5919-1-git-send-email-rth@twiddle.net> (raw)
While continuing to work on the sparc64 on i686 problem, I've run into
a few things that could be done better.
I haven't done any proper measurements of memory usage or boot time,
but all together my guess is that this saves 10-20k. Not much, I grant,
but maintaining more cache locality ought not hurt.
