WebSphere is playing it cool, man !

An homage to John "cool man" Stecher.

When everyone knows you're the fastest, you can play it cool.

WebSphere Application Server V7.0 GA'd in October. A couple weeks later IBM publishes an overall leadership SPECjAppServer2004 score of 20179 JOPS@Standard. Now, a month later, if you google "SPECjAppServer2004 20179" you won't find a single hit ... well, maybe now you will. Hm, a little more digging and I see that SPEC uses different score formats depending on how the data is queried. The score is also reported as 20178.61 JOPS@Standard which does give me a couple of hits.

Damn, I thought WAS was going for the ultimate cool, man.

SPECjbb2005 Bragging Rights for IBM J9

With the release of IBM Java 6 SR3, and its availablility on Windows via Websphere Application Server 7.0.0.1, J9 has extended its SPECjbb2005 lead over JRockit to 11% on Intel and has trumped its own leading result on AMD by 10%.

IBM J9 has

• leadership 1,2,4,8,16,32 & 64-core results (IBM System p and System i)
• leadership 4 and 8-core Intel results
• leadership 8 and 16-core AMD results
• leadership 4-socket result
• leadership x86 2-socket result
  

Published results on Intel's Harpertown chip provide an interesting comparison of J9, JRockit and HotSpot. (Note the HotSpot number is using Sun's Java 6 _05 update. There hasn't been a publish with their faster _06 Performance update.)

J9's SR1 publish on the 3.16GHz Harpertown chip beats the more recent JRockit publish on the 3.33GHz chip. Also of interest are the uses of 32 and 64-bit JVMs. J9's 64-bit SR3 number beats JRockit by 11% and J9's 32-bit number beats JRockit by 6%.

J9 now has the leadership 8-core Intel number, the leadership 8-core AMD number and the overall leadership 8-core number using an IBM POWER6 chip.
With Sun's Niagara-2 processors having 8 cores per socket, Sun has published a number of leading per-socket scores. With the recent publish on IBM's Bladecenter LS42, IBM and J9 now claim the leadership 4-socket result:Sun is still leading the 2-socket category ... by 2% ... using twice the number of cores and 16 times the number of threads.
J9 has the overal leadership 16-core result as well as the leading x86 16-core result.

oh .. if you actually read this far and are wondering what we did in SR3. The 10% boost is from the Apache Harmony improvement to TreeMap discussed in David Dagastine's blog.
