It's a minor disappointment, but no great problem.  The machine's primary 
job is as a firewall/router, although I'd like to run some more 
CPU-intensive processes like Snort if I could do it without getting bogged 
down.

5.3-STABLE (as of last December).  I upgraded from 4.x mainly to get the 
newer version of GCC.

I actually saw a pretty nice jump from -O2 to -O3 in the OpenSSL benchmarks.  
That was my main motivation.

True, but although I still don't know a lot about Alphas beyond what was 
required to get this machine up and running, I'd have thought it'd have a 
comparable throughput per cycle.  Like you mentioned earlier, though, GCC 
may not be the ideal compiler for this system.
