bodhi updates push process

Bodhi's push process is something that is usually quite opaque to Fedora package maintainers. Once an update request goes into bodhi, the developer sits back and waits for the update to go to where it needs to go. The ball is then in releng's court, as they must sign the packages, and tell bodhi to begin the push. From there, bodhi does it's thing for a while, and then updates magically end up on our users machines. Yay!

Pushing updates used to take the better part of a day, mostly due to dumb code and lots of filesystem churn over NFS. Thankfully, a lot of the code is now much smarter, and people like jkeating and mmcgrath have been helping to address the NFS & infrastructure bottlenecks.

Hopefully I can help shed some light on one of the dark corners of bodhi known as The Masher. Here are some statistics of the last updates push that happened earlier today.

Initial push request from releng
Check koji tag / bodhi status consistency	38s
Move all of the build tags in Koji	9m32s
Update the comps CVS module	11s
Mash f9-updates-testing	4m16s
Mash f9-updates	1h3m8s
Mash f10-updates-testing	12m43s
Mash f10-updates	37m51s
Set update ids, state modifications, updates-testing digest generation	1m57s
Generate updateinfo.xml	5m55s
Repo sanity checks & symlinking to go live	1m4s
Cache latest repodata, and remove old	1m14s
Wait for updates to hit the master mirror	1h1s
Send update notices, update/close bugs, notify developers/commenters	11m11s
Total	3h49m42s

So we've obviously made some great improvements here, and once the signing server is deployed, you can probably expect a much more frequent/consistent flow of updates. However, I definitely think there is still a lot of low-hanging fruit in this process, and many steps can probably be done in parallel. We're going to be adding DeltaRPM generation into the mix in the near future, so I'll give an update a bit later with some details as to how that effects the process.

Anyway... if you know Python, and enjoy optimizing code -- come talk to me :)

ThinkPad X300 vs Z61t vs T43

So I recently purchased a shiny new Thinkpad X300 to replace my T43. I must say that the X300 is an absolutely incredible machine, but I'll let the graphs speak for themselves :)

Below are the results of some benchmarks that I ran comparing the Thinkpad X300, Z61t and T43. All machines were running Fedora 8 using the 2.6.24.3 kernel. CPU benchmarks were done using hardinfo, and disk benchmarks done with bonnie++. Graphs created with flot.
