Thought I'd give you some feedback in the form of data on a recent jump
in core size. I run a hunchentoot webserver on a (very) small dedicated
server. That machine is running SBCL 220.127.116.11 and generates a core that
I recently upgraded SBCL at home to 18.104.22.168. When I built the same
webserver on that machine the core is now 74.2M.
The dedicated server is a P4. The home machine is an AMD-64, if that
makes any difference. I don't recall the previous version I was running
on the AMD-64, but believe it was around 1.0.31 and it generated a core
size for the webserver that was about the same as the dedicated machine
at that time.
It does seem to compile much faster though :)
