Subject: [Qemu-devel] [PATCH 0/4] qjson: save a lot of memory
Date: Fri, 20 Nov 2015 10:04:25 +0100 [thread overview]
Message-ID: <1448010269-21694-1-git-send-email-pbonzini@redhat.com> (raw)
This patch from 2011 (!) saves about 96% of the allocation cost (down
from 500 MiB to 20 MiB) for check-qjson.

Paolo Bonzini (4):
qjson: replace QString in JSONLexer with GString
qjson: do not save/restore contexts
qjson: store tokens in a GQueue
qjson: surprise, allocating 6 QObjects per token is expensive
