$FreeBSD$
The cryptotest program repeatedly encrypts and decrypts a buffer
with the built-in iv and key, using hardware crypto. At the end,
it computes the data rate achieved. Operations are carried out by
making ioctl calls to /dev/crypto.
For a test of how fast a crypto card is, use something like:
cryptotest -z 1024
This will run a series of tests using the available crypto/cipher
algorithms over a variety of buffer sizes. The 1024 says to do
1024 iterations. Extra arguments can be used to specify one or
more buffer sizes to use in doing tests.
A sample run is:
0.129 sec, 2048 des crypts, 8 bytes, 127120 byte/sec, 1.0 Mb/sec
0.129 sec, 2048 des crypts, 16 bytes, 253915 byte/sec, 1.9 Mb/sec
0.129 sec, 2048 des crypts, 32 bytes, 508942 byte/sec, 3.9 Mb/sec
0.128 sec, 2048 des crypts, 64 bytes, 1020135 byte/sec, 7.8 Mb/sec
0.134 sec, 2048 des crypts, 128 bytes, 1954869 byte/sec, 14.9 Mb/sec
0.142 sec, 2048 des crypts, 256 bytes, 3698107 byte/sec, 28.2 Mb/sec
0.190 sec, 2048 des crypts, 1024 bytes, 11037700 byte/sec, 84.2 Mb/sec
0.264 sec, 2048 des crypts, 2048 bytes, 15891127 byte/sec, 121.2 Mb/sec
0.403 sec, 2048 des crypts, 4096 bytes, 20828998 byte/sec, 158.9 Mb/sec
0.687 sec, 2048 des crypts, 8192 bytes, 24426602 byte/sec, 186.4 Mb/sec
0.129 sec, 2048 3des crypts, 8 bytes, 127321 byte/sec, 1.0 Mb/sec
0.131 sec, 2048 3des crypts, 16 bytes, 249773 byte/sec, 1.9 Mb/sec
0.128 sec, 2048 3des crypts, 32 bytes, 512304 byte/sec, 3.9 Mb/sec
0.128 sec, 2048 3des crypts, 64 bytes, 1021685 byte/sec, 7.8 Mb/sec
0.132 sec, 2048 3des crypts, 128 bytes, 1986511 byte/sec, 15.2 Mb/sec
0.142 sec, 2048 3des crypts, 256 bytes, 3695005 byte/sec, 28.2 Mb/sec
0.190 sec, 2048 3des crypts, 1024 bytes, 11024876 byte/sec, 84.1 Mb/sec
0.264 sec, 2048 3des crypts, 2048 bytes, 15887997 byte/sec, 121.2 Mb/sec
0.402 sec, 2048 3des crypts, 4096 bytes, 20850846 byte/sec, 159.1 Mb/sec
0.689 sec, 2048 3des crypts, 8192 bytes, 24333532 byte/sec, 185.7 Mb/sec
Expect ~400 Mb/s for a Broadcom 582x for 16K buffers on a reasonable
CPU. Hifn 7811 parts top out at ~120 Mb/s. Performance depends
heavily on memory and bus performance.
This code originally came from openbsd; give them all the credit.
