As I understand it, elf makes it easier to produce dynamic libs -> some memory savings when I run lots of apps. I also read somewhere that someday it would be a x86 common format. What does that mean? Can I take any Solaris x86 binary and run it under Linux? I don't think so...(Too good to be true) Are there any other reasons for wanting elf? /Anders -- ____________________________________________________________________ / / \ / Anders Eriksson and...@lulea.trab.se Voice: +46 92075403 /___\ | Snail mail: Telia Research AB, Aurorum 6, S-977 75 Lulea, Sweden |

It's hard to believe that this nice extension won't cost anything. With my minimal system (486DX/2 with only 8 Mb) this is very important. -- Die Grenzen meiner Sprache bedeuten die Grenzen meiner Welt. - L. Wittgenstein

I don't know about Solaris but SCO binaries running under iBCS/Linux on a 486DX-33 show similar system call overhead to SCO on a 486DX-50 (Larry Wall's lmbench suite). Given that an equivalent Linux system tends to have a smaller kernel and more shared library use by the system daemons so has more pages of memory free and that Linux uses a dynamically sized disk caching strategy you typically see a *gain* in performance where applications are doing other than running their own code. Yeah, emulation has a cost - a native Linux binary has half the system call overhead for instance. But the cost compared to the native OS is negligible. Mike
