Could this be Michael's > problem? No. What machine does he use? Also, gzip optionally can use x86 assembly code that comes with it, and turning it off (or on) often makes a difference. The question is how suse have compiled their binary, and unless you know this, speed comparisons are not feasible. -----==- | ----==-- _ | ---==---(_)__ __ ____ __ Marc Lehmann +-- --==---/ / _ \/ // /\ \/ / pcg AT goof DOT com |e| -=====/_/_//_/\_,_/ /_/\_\ --+ The choice of a GNU generation | |
