Michael McCandless commented on LUCENE-1591:
--------------------------------------------
bq. Did you run EnwikiDocMaker on the actual XML or the bz2 archive?
I downloaded the bz2 2008036 Wikipedia export, ran bunzip2 on the command line,
then had to patch Xerces JAR to get it to parse the XML successfully.
bq. I run the test on my TP 60, which is not a snail-of-a-machine, but
definitely not a strong server.
Hmm -- I wonder how long bunzip2 would take on the TP 60. Time to upgrade ;)
Get yourself an X25 SSD!
bq. I would have done that, but the output XML is 17GB, and doing it twice is
not an option on my TP. That's why I wanted this bzip thing in the first place
Ahh OK :)

> bzip compression can aid the benchmark package by not requiring extracting
> bzip files (such as enwiki) in order to index them. The plan is to add a
> config parameter bzip.compression=true/false and in the relevant tasks either
> decompress the input file or compress the output file using the bzip streams.
> It will add a dependency on ant.jar which contains two classes similar to
> GZIPOutputStream and GZIPInputStream which compress/decompress files using
> the bzip algorithm.
> bzip is known to be superior in its compression performance to the gzip
> algorithm (~20% better compression), although it does the
> compression/decompression a bit slower.
> I wil post a patch which adds this parameter and implement it in
> LineDocMaker, EnwikiDocMaker and WriteLineDoc task. Maybe even add the
> capability to DocMaker or some of the super classes, so it can be inherited
> by all sub-classes.
