afaik, strip(1) just removes certain sections from the ELF
file. presumably these sections are not loaded into memory unless
required.
on a .so (or .o), it removes symbols from the exported list, which
presumably makes it a little faster to link to (negligible). i don't
think it actually removes the code behind those symbols.
of course, with smaller files, you're more likely to get more frequent
disk cache hits, etc - so there will also be a (negligible) speed up
there.
core dumps on the other hand, have nothing to do with size or run-time
speed. presuming you delete old core files, there is no good reason to
have core dumps disabled.
