I am using a 4501 with the accelerator and when it works I agree it
can easily saturate a T1/E1.
The only problem is the card randomly wedges (personal observations
on 3.7 to current) so I've been advised to effectively shut the card
off (kern.usercrypto=0).

that would tend to make things worse anyway - you'll just increase
the
rate of interrupts and that seems to be the main problem.
for a something fast like "aes" it might be true, for 3des this
statement
ist wrong.
never did stuff with the 45xx but I can remember that for pushing
1mbit/s
3des I needed 133MHz on old 486er CPU and a P1-166MMX could barely
handle
2mbit/s. so with the accelerater you can handle T1/E1 easily,
without it
you are lost. some benchmarks from years ago...
bye, siggi.
