Fasl loading is somewhat slow, but for me

* (time (require :asdf))

Evaluation took:
  0.892 seconds of real time
  0.165764 seconds of user run time
  0.036642 seconds of system run time
  [Run times include 0.005 seconds GC run time.]
  0 calls to %EVAL
  0 page faults and
  18,510,816 bytes consed.
("ASDF")

and

* (time (require :sb-bsd-sockets))

Evaluation took:
  0.94 seconds of real time
  0.359362 seconds of user run time
  0.048002 seconds of system run time
  [Run times include 0.025 seconds GC run time.]
  0 calls to %EVAL
  0 page faults and
  26,330,440 bytes consed.

so possibly your system is slightly underpowered, or maybe you are
loading things from a slow network share?

For saved images 2-3 seconds sounds abnormally slow (unless a fair
deal for shared object loading & foreign symbol resolution is taking
place), but impossible to diagnose without more details. (What is in
the image? Is .sbclrc getting loaded? Etc.)

No network drive, but I did see a lot of page faults. (I haven't run 
sbcl for a while.)

As far as a slightly underpowered system, it would really surprise me if 
you need a lot of power just to load basic libraries like this. Isn't 
there a way to do this faster? Is there something comparable to .so's 
where the functions are fixed in memory and everything is compiled and 
optimized already?

I don't have anything in my .sbclrc. It's missing on my system.
