"Roger Vossler" rvossler@qwest.net is widely believed to have written:
While modularity usually gains a certain amount of flexibility, theprice paid is a big hit in performance.
What gives you this idea?
In the particular case of Squeak plugins, the lookup when an external prim is first called might involve finding a file loading it, doing an OS binding/search etc, but that only happens once. On susequent uses, the cost is rather small - an extra couple of indirections perhaps.
In the case of Smalltalk code modules of the sort we have been discussing recently, I imagine that any sensible mechanism will effectively be as fast as any other method lookup.
What cases of a modularity cost have you seen?
