Subject: Re: [PATCH] short benchmarks
Date: Thu, 20 Nov 2008 03:26:16 +0100	[thread overview]
Message-ID: <4924CAC8.1070504@online.de> (raw)
In-Reply-To: <12271034142436-git-send-email-zbr@ioremap.net>

Hello,

here some short benchmarks with the new HIFN 795x driver:
---------------------------------------------------------
Hardware which I use:  net5501-70 with vpn1401 (PCI-Card)
                       (Users with vpn1411 mini-pci-card, please
                        report it if the driver works with this card.)

Software which I use:  Latest stable kernel 2.6.27.6 from
                       www.kernel.org.

Chiper: aes-cbc-essiv:sha256, keysize: 256 bits

With hifn_795x driver:
----------------------------------------------------------------------
(/misc is mounted to the crypted partition)

piepmatz:/misc# time dd if=/dev/zero of=xxx.img bs=1024 count=700000
700000+0 Datensätze ein
700000+0 Datensätze aus
716800000 Bytes (717 MB) kopiert, 68,0707 s, 10,5 MB/s

real    1m9.206s
user    0m0.536s
sys     0m7.312s
piepmatz:/misc# time cat xxx.img >/dev/null

real    1m12.737s
user    0m0.080s
sys     0m2.596s
piepmatz:/misc#

----------------------------------------------------------------------


===========================================================================

As referece the software implementation of AES:

---------------------------------------------------------------------------
piepmatz:/misc# time dd if=/dev/zero of=xxx.img bs=1024 count=700000
700000+0 Datensätze ein
700000+0 Datensätze aus
716800000 Bytes (717 MB) kopiert, 128,616 s, 5,6 MB/s

real    2m8.711s
user    0m0.616s
sys     0m6.652s
piepmatz:/misc# time cat xxx.img >/dev/null

real    2m2.761s
user    0m0.080s
sys     0m2.368s
piepmatz:/misc#
---------------------------------------------------------------------------

With the HIFN 7955 crypto engine the throughput is 10,5 MB/s, nearly
the double of the software implementation of AES. Therefore the time
is nearly the half.

Regards
Andreas Gerlich
