Alternately, instead of believing someone's opinion, we could ask the data in question: % ls -l 248643584 Sep 17 00:03 5.0-CURRENT-20020917-JPSNAP.iso 212988130 Oct 13 10:39 5.0-CURRENT-20020917-JPSNAP.iso.gz Compression gets rid of about 36MB. That's 3.4 hours saved on a 28.8K modem download time, overall... a 14% reduction in size. I guess it's no wonder it's a frequently asked question. Too bad it's not answered correctly in the FAQ. I think the correct answer is maybe "because the FAQ maintainers have broadband connections"... PS: If the server is overworked, all you need to do is store the compressed version of the image on the server; I have no idea why you seem to believe that it needs to be compressed more than once, so whether or not the server is "overworked" is irrelevent to the compression, I think. PPS: If the server is overworked, think what reducing the number of bytes per download by 14% would do for it. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
