The individually numbered files change sizes radically because I'm moving around start and end points. You can ignore that.
I am looking at piece 10 however to see why it's smaller: ah. I have a typo in the size for that one, I asked for only 200000 pages to go in it instead of the 240000 I intended :-D And so that's all that went in (minus deleted pages). Nothing's missing though; anything "extra" winds up in the last piece (15). You can look at the stub files to verify that.
FWIW we'll be juggling the number of pages per chunk on a regular basis.

Hi all,
Congrats Ariel! :) The sum of pages-meta-history files for the last two enwiki dumps are 342.7GB for the 20110115 dump and 353.5GB for the 20110317 dump, which shows that the overall dump size grew over 2 months. Seven of the individually numbered pages-meta-history files reduced in size while eight increased in size from 20110115 to 20110317. By far the biggest decrease was the pages-meta-history10.xml.bz2 file which dropped from 18.7GB down to 1.9GB. I think there is probably missing revisions in that page ID range.
Here are some historical dumps sizes for comparison to show the growth of these files:
enwiki-20060816-pages-meta-history.xml.7z 5.08GB enwiki-20070402-pages-meta-history.xml.7z 11.3GB (229 days since previous dump) enwiki-20080103-pages-meta-history.xml.7z 17.2GB (276 days since previous dump) enwiki-20100130-pages-meta-history.xml.7z 31.8GB (758 days since previous dump) enwiki-20110115-pages-meta-history[1-15].xml.7z 38.0GB (350 days since previous dump) enwiki-20110115-pages-meta-history[1-15].xml.7z (7z compression in progress)
Here's a graph of this data showing the dump file size growth seems to be pretty linear: (chart x-axis starts from 20060816 dump and ends at 20110115 dump) "http://nekrom.com/wikipedia/enwiki%20history%20dump%20file%20size% 20over%20time.png"
cheers, Jamie

Well, that used up all my good luck for the year, but the bz2s are ready for download. The md5sums are still calculating, give them a couple hours to show up. If all continues to go well we'll have the 7z files in 4-5 days.
As before I do not plan to provide a single 350gb file of the bz2, nor a single 7z file for download.
Happy trails,
Ariel
