19:11:45|3b|flip768: that comment is about decompressing from a stream, 3bz decompresses from normal files reasonably quickly using mmap. 3bz doesn't currently have an API for reading the decompressed data as a stream, but that does sound useful, will consider adding that at some point
19:13:21|3b|from the profile you pasted, it looks like mostly gray-stream overhead, not sure if i'd be able to avoid that if i added it to 3bz though
19:15:24|3b|does seem to be lots of room for improvement in that profile at least
