Thank you so much for the kind words, refreshing.
Here is the latest sqlar result on Linux source code on the same test machine in warm state:
sqlar: 268 MB, 30.5 s
Pack: 194 MB, 1.3 s
Very good result compared to tar.gz. And much better than ZIP, considering sqlar gives random access like ZIP and unlike tar.gz. I considered sqlar as a proof of concept, and it inspired me to create Pack as a full solution. I always agreed with the great drh (creator of SQLite) points about SQLite as a file format, and Pack is a try to demonstrate that.
I made Pack to give people a better life (at least behind their desks), and as you do, I hope people get to use it and find it useful.
