I know that this was talked a lot and recently Mark Callaghan also gave a session in MySQL user conference 2008 about the real bottlenecks.

Other day I was testing my thread pool stuff with MySQL 5.1.24 + InnoDB plugin 1.0.1 along with other miscellaneous benchmark tests by making them CPU bound by keep the working set completely in memory to gauge the performance of threads overhead; and on 8-core box InnoDB seems to be doing better than 4-core. And then immediately I started few tests with mysqlslap by keeping complete data set in the buffer pool to get the proper timing on locking overhead.

Here is the comparison of performance on 8-core box with innodb_thread_concurrency is set to 32 and 0 for variable threads on 64-bit Redhat Linux 4 . The same box is used as …

I have released PBXT 1.0.03 Alpha and it is available for download from http://www.primebase.org/download. I have also posted binary plugins for a few platforms.

If you are building from source I have added a Quick Guide: Building and Installing PBXT from Source, which I hope makes the task really simple. If not, I would appreciate any feedback!

With this version I have completed the implementation of full-durability, and other features that are scheduled for RC and ultimately for the first GA release.

Still to be done is the Windows port which I plan to do before the first Beta release.

Please send any comments, questions, bug reports, etc. directly to me: paul dot mccullagh at primebase dot org.

Yesterday, I became a Google employee.I know that there has been quite a hiatus in my MySQL related activities but it wasn't all without good reason. The first proper holiday I have had in a few years.Tomorrow afternoon, I hope to spend some time with Mark Callaghan ... It would be a nice break from the new-employee orientation and tutorials and hopefully a chance to meet more of my new

As Farhan has already pointed out to us, Disaster is Inevitable - Must shutdown generators. My primary hosting provider The Planet had a serious meltdown, 9,000 servers unavailable, DNS and administration application .

My server was effectively totally unavailable from 3PM Saturday until 10AM Monday, 43 hours in total.

The problem didn’t stop there. Started and verified servers and domains, but like 8 hours later I find that the DNS is wrong on two important domains (I didn’t discover this because I have them in local /etc/hosts) because I moved them to a different IP like 2 weeks ago.

The Planet denied any problems, ticket logged to get them fixed because admin interface was still down.
Wind forward, …

Hi. My name is Brian, and I’m a tech bibliophile.

I have owned more books covering more technologies than I care to admit. Some of my more technical friends have stood in awe of the number of tech books I own. I am also constantly rotating old books that almost *can’t* be useful anymore out of my collection because there’s just no room to keep them all, and it would be an almost embarrassingly large collection if not for the fact that I have no shame or guilt associated with my need for dead trees.

If you need further proof:

• I have, on more than one occasion, suggested to my wife that we take a walk around our local mall so I could browse the computer section of the book store, not to buy, but just to keep up with the new titles and stuff.
• Ok, I usually buy.
• I also go into book stores whenever I’m out of town to get a comparison of what seems to be popular in different areas of the …

UPDATE: if anyone knows of a non-broken syntax highlighting plugin for wordpress that supports bash or some other shell syntax, let me know :-/

Apache logs, database backups, etc., on busy web sites, can get large. If you rotate logs or perform backups regularly, they can get large and numerous, and as we all know, large * numerous = expensive, or rapidly filling disk partitions, or both.

Amazon’s S3 service, along with a simple downloadable suite of tools, and a shell script or two can ease your life considerably. Here’s one way to do it:

1. Get an Amazon Web Services account by going to the AWS website.
2. Download the ‘aws’ command line tool from here and install it.
3. Write a couple of shell scripts, and schedule them using cron.

Once you have your Amazon account, …
