Searching compressed text

Lzgrep search compressed text without uncompressing. If it is faster than zgrep which uncompress the file before do grep, it's usable. This paper say lzgrep is upto 50% faster than zgrep. I roughly tested on apache logs which is compressed by gzip. On most of case, lzgprep is only 10% faster than zgrep.
