I've tried akcl (1.615 on Linux, 486DX2,50MHz, 16+16MB and Xakcl 1.605 on
different SPARCs) and in comparison to CLisp it is definitively *much*
slower *and* uses much more memory!!! (e.g Xakcl: 5MB, 52.35sec;
Clisp: 1.5MB, 10sec for the same problem on a SPARCstation 1). 
I am working on an AI planning-system, so I don't know, if the situation 
is different for programs with extensive numeric computation, 
but I really doubt that.
