gzunip -c and gzcat

Could anyone tell why is gunzip -c so much slower t开发者_JAVA技巧han gzcat ?

I though they were essentially the same..

cheers,

They provide the same functionality, and it would not surprise me if they were the same executable (certainly zcat and gunzip are on my linux box).

I wonder how you have measured the performance? Are you seeing performance differences due to disk caching, or some other external influence?
