Re: [Bug-tar] Use posix_fadvise to improve archive creation performance

[Paul Eggert]

I've lost context. I prefer not having this depend on an environment 
variable.

Can't the filesystem in question be fixed to have decent performance in 
the typical case where applications access files sequentially? It's not 
like 'tar' is a special case. I'd hate to have to modify lots of 
programs just to work around a lame filesystem.
