Re: [9fans] Go 1.3b1 cmd/pack test takes too long
thanks; i should have checked that. running it on the fossil+venti server brings it down a bit. still, it's not stellar. bootes% go test PASS ok cmd/pack 81.480s bootes% go test PASS ok cmd/pack 79.719s On Sun, May 4, 2014 at 7:51 PM, Anthony Martin al...@pbrane.org wrote: Skip Tavakkolian skip.tavakkol...@gmail.com once said: is anyone else seeing similar results for cmd/pack? % go test PASS ok cmd/pack 172.505s this is on an atom (d525 @ 1.8ghz, 4gb). same test on an arm (quad core a9 @ 1.7ghz, 2gb, linux 3.8) takes much less time: % go test PASS ok cmd/pack20.872s Your numbers don't look entirely abnormal. That test issues over a million small writes. (Although it really should be using bufio). How is your system set up? Are you getting your fs from the network? The Plan 9 disk file systems are pretty slow even when used locally. Anthony

Are you suggesting we ought to change pack? I don't mind doing it if it's likely to be accepted by the developers. On NetBSD and my slow Plan 9 network, there are a few places that trip up the tests because they seemingly take too long, if buffering would speed them up, I would be a lot more comfortable. yes. a million small writes in a test like that is unreasonable. - erik
