Subject: [PATCH 0/4] crypto: improve performance of ciphers in XTS mode
Date: Thu, 17 Oct 2019 15:56:50 +0100 [thread overview]
Message-ID: <20191017145654.11371-1-berrange@redhat.com> (raw)
Currently QEMU uses its own XTS cipher mode, however, this has
relatively poor performance.
Gcrypt now includes its own XTS cipher which is at least x2 faster than
what we get with QEMU's on Fedora/RHEL hosts. With gcrypt git master, a
further x5-6 speed up is seen.
This is essential for QEMU's LUKS performance to be viable.
Daniel P. Berrangé (4):
tests: allow filtering crypto cipher benchmark tests
tests: benchmark crypto with fixed data size, not time period
crypto: add support for gcrypt's native XTS impl
crypto: add support for nettle's native XTS impl
