Subject: [PATCHSET for-next] Add alloc cache for sendmsg/recvmsg
Date: Thu, 7 Jul 2022 17:23:42 -0600 [thread overview]
Message-ID: <20220707232345.54424-1-axboe@kernel.dk> (raw)
Hi,
This abstracts out the alloc cache we have for apoll entries, and extends
it to be usable for recv/sendmsg as well. During that abstraction, impose
an upper limit for cached entries as well.
This yields a 4-5% performance increase running netbench using
sendmsg/recvmsg rather than plan send and recv.
Post 5.20, I suspect we can get rid of using io_async_msghdr for single
vector sendmsg/recvmsg, which will make this less relevant. But as this
work isn't done yet, and the support for eg ITER_UBUF isn't upstream yet
either, this can help fill the gap.
