Cryptoapi version of AES is slowest implementation of AES that I know of.
For speed tests, please compare against more modern implementation.
Below is one old AES128 speed test that I ran on my 300 MHz test box:
KERNEL IMPLEMENTATION MODE WRITE MiB/s READ MiB/s
2.6.1 cryptoloop single-key 5.21 4.08
2.6.1 loop-AES single-key 9.52 7.56
2.6.1 loop-AES multi-key(MD5 IV) 7.67 6.35
2.4.22aa1 loop-AES single-key 10.55 10.16
2.4.22aa1 loop-AES multi-key(MD5 IV) 8.75 8.13
The cryptoloop implementation is busted in more than one way, so it is
useless for security needs:
