20:26 Looking on 5.4 - IO bound benchmarks » MySQL Performance Blog

With a lot of talks around 5.4 I decided to check how it works in our benchmarks. For first shoot I took tpcc-like IO-bound benchmark (100W, ~10GB of data, 3GB buffer_pool) and tested it on our Dell PowerEdge R900 box (16 cores, 32GB of RAM, RAID 10 on 8 SAS 2.5″ 15K RPM disks). For comparison I took XtraDB-release5 and 5.0.77-highperf percona release.

For raw results you can check my Google Spreadsheet (it is also being update with my next CPU benchmarks, and benchmark on SSD & FusionIO), also I post graph there:

Results are in TPM (transactions per minute, more is better).

So I can confirm that MySQL team did great job with 5.4 and it shows the best results.
Some more results you can find on Dimitri’s blog, one of Sun Performance Engineers.

From our side we will look on recent improvements and also on Google V3 patches and will integrate them into next release of XtraDB, so stay tuned :)

13:24 Make Friends with BuddyPress » WordPress Development Blog

What if there was software with the elegance and extensibility of WordPress but all the features you’ve come to expect from social networks like Facebook? Now there is: check out BuddyPress.

BuddyPress is an official sister project of WordPress. The idea behind it was to see what would happen to the web if it was as easy for anyone to create a social network as it is to create a blog today. There’s been an explosion of social activity on the web, it’s probably the most important trend of the past few years, but there’s been a dearth of Open Source tools that enable the social web.

In WordPress we have a robust and extensible base that can scale to many millions of users, and BuddyPress is essentially a set of plugins on top of WordPress that add private messaging, profiles, friends, groups, activity streams, and everything else you’ve come to expect from your favorite social network, like a Facebook-in-a-box.

I don’t think BuddyPress will be something you use instead of your existing social networks, I mean all your friends are already on Myspace, but if you wanted to start something new maybe with more control, friendlier terms of service, or just something customized and tweaked to fit exactly into your existing site, then BuddyPress is a great framework to use. Maybe even someday you’ll be able to connect your BuddyPresses to each other and to the existing monolithic social networks.

This is just a 1.0 release and it’s not for everybody yet, for example it currently requires using MU which is a bit trickier to get set up than regular WordPress, but regardless I’d recommend diving into the community at BuddyPress.org, which is great example of the software in action.

Here’s Andy’s official announcement post.

08:19 Design Tweaks Poll Results » WordPress Development Blog

The poll is closed, the votes are counted, and the results are interesting. The table below shows the actual breakdown of the poll votes, of which there were 2,651. As you can see, there were four main contenders: Dean J. Robinson’s Fluency-based submissions (two variations), the existing 2.7 interface, and Matt Thomas’s comp (MT), which exists somewhere between them in terms of style. Note: GB was a late entry, and was posted after over 900 votes had already been collected.

The voting results

Top two submissions by Robinson and Thomas

As several people have rightly pointed out, the Fluency-style designs not only took the top spot, but in combination added up to a higher percentage than any other. We’re not focusing solely on that statistic, though, because had other designers submitted multiple versions, the numbers might have looked different. What was most interesting for me was checking in on the votes over the course of the two days the poll was open. The top three (Fluency-dark, Current 2.7, MT) kept beating each other out for the #1 spot as they cycled back and forth through the top three slots, and had the poll closed on time (left it open a little longer in case anyone translated the time zone incorrectly), the order would have been a bit different.

What’s more interesting to me is the overall style that seems to be preferred among voters, as Matt’s comp has some stylistic similarities to Dean’s (see image at left). It also would be interesting to know how many of the votes for the current 2.7 interface were based on thinking it looked the best vs. how many were votes against changing the interface at all so soon after the 2.7 redesign. If you want to comment on what you liked best and/or least about any of the designs, this thread is a good place.

So what happens now? However we look at it, the Fluency-style designs clearly have a lot of fans. Then again, so do the designs of Matt Thomas (he’s behind the current style of 2.7, remember, in addition to the comp labeled MT). To give the interface the attention it is due, and to take seriously some of the interface feedback around usability and accessibility, we’re going to leave the looks alone for 2.8. It’s our guess that a revised style will make into 2.9 early in the development cycle to allow us plenty of time for user testing and revision. How close it winds up being to the comps submitted in this design tweaks challenge will depend, but in the meantime:

Congratulations, Dean J. Robinson, on winning the vote!
