400MHz PXA255-based gumstix compared to Intel PCs

The nbench CPU benchmarking utility (with floating point tests disabled, since the gumstix CPU has no FPU) yields:

TEST	Iterations/sec.	Old Index	New Index
		Pentium 90	AMD K6/233
NUMERIC SORT	152.44	3 .91	1.28
STRING SORT	10.753	4.80	0.74
BITFIELD	3.6149e+07	6.20	1.30
FP EMULATION	13.023	6.25	1.44
IDEA	393.08	6.01	1.79
HUFFMAN	21.716	0.60	0.19

Baseline: Pentium 90 with 256 KB cache running MSDOS
Baseline: AMD K6/233*, 512 KB L2-cache, gcc 2.7.2.3, libc-5.4.38, Linux 2.0.32

Conclusion: generally about the same speed, or slightly faster, than a 233MHz K6, or about 4-6 times the speed of a Pentium 90.

600MHz PXA270-based gumstix compared to Intel PCs

The nbench CPU benchmarking utility (with floating point tests disabled, since the gumstix CPU has no FPU) yields:

TEST	Iterations/sec.	Old Index	New Index
		Pentium 90	AMD K6/233
NUMERIC SORT	198.12	5.08	1.67
STRING SORT	17.469	7.81	1.21
BITFIELD	6.6802e+07	11.46	2.39
FP EMULATION	41.583	19.95	4.60
ASSIGNMENT	1.2438	4.73	1.23
IDEA	538.49	8.24	2.45
HUFFMAN	302.12	8.38	2.68

Baseline: Pentium 90 with 256 KB cache running MSDOS
Baseline: AMD K6/233*, 512 KB L2-cache, gcc 2.7.2.3, libc-5.4.38, Linux 2.0.32

Conclusion: generally about twice as fast as a 233MHz K6, or about 8-10 times the speed of a Pentium 90.

OpenSSL

Using the openssl built-in benchmarking routines, we get the following results for 100, 200, and 400MHz operation:

The numbers in the first set of tables are in 1000s of bytes processed per second.
