Interesting, that was a significant improvement. Almost as good as zip and certainly good enough to make 7za a good candidate. Thanks.
I'm running a lengthy test right now, but my immediate impression is that 7zip is only marginally slower than zip. Zip typically needs slightly less than 0.02seconds for an extraction, where as 7zip typically needs a little more than that. If 7zip does better compression too (which it should), it's a winner. However, 7zip for Linux looks a bit, well, unfinished. It doesn't read filenames from stdin, it doesn't have a --quiet option,
I use '-bd -y' for "quiet" opperation in scripts.
and it's still called 'beta'. Makes me a little wary.
It's been called that for several years now (for as long as it exists really). During that time I have been using it on several servers for all kinds of archiving jobs, and never noticed any real problems. Like where an archive was damaged and files inside it couldn't be extracted anymore... That never happend.
