That took about 54 hours on an EC2 2.5x unit CPU. The final data size is 5469GB.
As the process just finished I haven't been able to check the integrity of the XML, however, the bzip stream itself appears to be good.
As was mentioned previously, it would be great if you could compress future archives using pbzib to allow for parallel decompression. As I understand it, the pbzip files are reverse compatible with all existing bzip2 utilities.
Yes, they're :-).

Thanks again for all your work on this! Kevin

New full history en wiki snapshot is hot off the

It's currently being checksummed which will take a
while for 280GB+ of
compressed data but for those brave souls willing
to test please grab it
from
http://download.wikipedia.org/enwiki/20100130/enwiki-20100130-pages-meta-his...
and give us feedback about its quality. This run
took just over a month
and gained a huge speed up after Tims work on
re-compressing ES. If we
see no hiccups with this data snapshot, I'll start
mirroring it to other
locations (internet archive, amazon public data
sets, etc).
For those not familiar, the last successful run
that we've seen of this
data goes all the way back to 2008-10-03. That's
over 1.5 years of
people waiting to get access to these data bits.
I'm excited to say that we seem to have it :)
So now that we've had it for a couple of days .. can I
get a status
report from someone about its quality?
Even if you had no issues please let us know so that
we start mirroring.
