Well it looks like the ASF has finally ran out of it patience with the Java Community Process and Sun’s refusal to allow Apache to use the TCK (Test Certification Kit) to certify it’s open JVM ‘Harmony’ with.
This is after 7 months of trying to reach a conclusion privately to something in a signed contract!
For me this sounds like a bit of a division inside of Sun. You have one part saying they want to be Open and Free, and harness the power of Open Source. This camp is responsible for releasing Tomcat, and getting Apache to participate in the JCP. They recognize what a open community can do, and the power of having multiple companies actively developing something.
You then have the old guard. These are the people who have revenue targets from J2SE licenses. They see this as a loss of potential royalty which would affect their bonuses, and a loss of control. No wonder they are baulking on their contract.
I guess Sun needs to answer the question.
Do you want to be open so that other companies have the freedom to use the JDK as they see fit (including commercial purposes).
to rephrase.. do you want to be owner of a small pie, or a participant of a much larger one?
personally I would prefer the bigger pie.
It will be interesting to see which Sun chooses.
(as well as how they try to spin this into a GPL/ASL war, which it isn’t it’s a contract dispute)

Robert Cringley’s prediction of google creating a data centre in a shipping container has been fulfilled.
not by google, but by sun.
Project Blackbox was announced today.
I’m waiting for the day for a operations engineer to say ‘we need to swap out container 5 as it is malfunctioning’, in the same manner they talk about a malfunctioning computer.
I think sun is going in the right direction here, and addressing the real problem, data center operations directly instead of focusing on incremental improvements like it’s competitors are.
way to go Jonathan and team!

Well.. the time has come.. my Try & Buy period is over.. and it is time to return the machine. It’s going to be picked up today.
It’s a shame that sun hasn’t updated it’s winners page I’m guessing they have got enough marketing exposure from Colm (who interestingly couldn’t even officially participate due to him living in Ireland).

I’ve been checking the sun winnners about once a day to see if I have won (or who did) and I noticed a couple of changes. (they could have been there all the time, I’m not sure)
- You can now enter with a T1000, which is a smaller 1U offering. Thankfully it looks like they will allocate 1 machine each (ie.. there are 9 T1000’s and 9 T2000’s on offer, not just 9 machines)
- This line is a bit sucky …
If Sun does not receive a sufficient number of eligible submissions during an Entry Period, Sun may, in its discretion, combine two Entry Periods and consider all of the submissions as having been received during both Entry Periods.
Why am I checking so regularly.. well first off all I’m impatient, but my Try&Buy period is about to expire and don’t want to go to the hassle of shipping it back only to turn around and get it returned to me the next day. (and I definatly don’t want a $AUD13k charge on my credit card)
I’m guessing I haven’t won :-(, as I haven’t got a official email from sun yet. Good luck to whoever won it!

If you have been reading my previous entries the answer you will think is ‘not bloody well’.
After about 3 days of tuning we doubled the throughput, and got a much nicer picture, outperforming a x86-64 machine by 2.5 times in one case.
Thanks to Luojia Chen (Jenny) from Sun, Peter Zaitsev from Mysql, and Colm MacCárthaigh & Mads Toftum from the ASF.
oh.. the benchmark.. I nearly forgot ;-)
(Oh people..please link to the blog entry, and not the paper itself.. Thanks)
update:
people were having issues downloading the PDF.
so I placed a mirror of it here

this is the output of
dtrace -n 'pid$target:::entry{ @[probefunc] = count() }'
when I run mysqlslap -c 20 -i 20
pthread_getspecific 365
malloc_internal 377
my_malloc 377
free 378
malloc 378
my_wc_mb_filename 399
my_no_flags_free 420
strmake 444
pthread_self 468
memset 582
alloc_root 630
strmov 651
strlen 655
memcpy 897

my_pthread_fastmutex_lock 936
mutex_lock 1133
mutex_lock_impl 1133
my_utf8_uni 1365
mutex_unlock 2069
I’m about to prepare a more formal analysis (and benchmark) about this. but in order for me not to compete with colm I’m going to wait until the 24th to submit it.
I switched to using sysbench as I thought there might be a bug in actual mysqlslap code, but it is also showing the same results.
those being mysql runs 10x slower on the sunfire than on a linux x86-64 machine.
If you are from sun, mysql, or a apache member, and want to check out the configuration to see how I screwed up, send an email from your @sun.com/@mysql.com/@apache.org email address with a public key and I’ll mail you the IP#/account details (ian at holsman.net).
the machine is only available while I’m awake (I live in Australia so it probably means your nighttime), as I haven’t put it in a colo (until I win it of course) and my ‘server room’ is my walk in robe.

ok.. now this is getting stranger.
I have 2 windows open, in one I get
$ mysqlslap --use-threads -psunfire -c 90 -i 500
Benchmark
Average number of seconds to run all queries: 2.180 seconds
Minimum number of seconds to run all queries: 0.779 seconds
Maximum number of seconds to run all queries: 4.497 seconds
Number of clients running queries: 90
Average number of queries per client: 0
and in the other i get
$ mysqlslap --use-threads -psunfire -c 90 -i 500
Benchmark
Average number of seconds to run all queries: 0.012 seconds
Minimum number of seconds to run all queries: 0.002 seconds
Maximum number of seconds to run all queries: 0.015 seconds
Number of clients running queries: 90
Average number of queries per client: 0
same machine, same user-id, same binary. the only difference is that mysql started in the ‘fast’ window.

and doesn’t seem to take it too nicely :-(
I decided to install the mysql beta on my laptop (Mac Intel @2G ram and 2GHZdual core) and my sunfire (@8G ram and 16 1GHZ Ultrasparcs).
(I have it installed on a x86-64 box as well, but that machine is busy at the moment)..
so for a quick sanity check I ran mysqlslap to see how it performs.
I chose to simulate a 20 concurrent users
sunfire$ mysqlslap -psunfire -c 20 -i 20
Benchmark
Average number of seconds to run all queries: 1.714 seconds
Minimum number of seconds to run all queries: 0.941 seconds
Maximum number of seconds to run all queries: 2.539 seconds
Number of clients running queries: 20
Average number of queries per client: 0
vs
laptop$ mysqlslap -i 20 -c 20
Benchmark
Average number of seconds to run all queries: 1.201 seconds
Minimum number of seconds to run all queries: 1.072 seconds
Maximum number of seconds to run all queries: 1.569 seconds
Number of clients running queries: 20
Average number of queries per client: 0
now.. before you get all pissy at me, these installs are both from mysql.com, are BETA release using ‘default’ setups..
I know they need tuning.
so I decided to run the mysqlslap against blastwave’s mysql5 (5.0.19) which has a bit better default setup (IMHO)
sunfire $ mysqlslap -c 20 -i 20
Benchmark
Average number of seconds to run all queries: 1.647 seconds
Minimum number of seconds to run all queries: 0.882 seconds
Maximum number of seconds to run all queries: 2.783 seconds
Number of clients running queries: 20
Average number of queries per client: 0
still the same kind of numbers.
one thing I did find interesting was that I only saw one connection in the SHOW PROCESS LIST command.
any mysql guru’s want to tell me what I’m doing wrong on the test here?
update: this is what I get on a x86-64 machine.
$ bin/mysqlslap -c 20 -i 20 -a
Benchmark
Average number of seconds to run all queries: 0.002 seconds
Minimum number of seconds to run all queries: 0.002 seconds
Maximum number of seconds to run all queries: 0.003 seconds
Number of clients running queries: 20
Average number of queries per client: 0
same deal.. no tweaking of configurations, just download the tarball from mysql.com and fire it up.
anyone have any ideas?

yes.. no more excuses.. time to open the box now.
If you want more photos see Ask’s
my Daughter Ainsley, will be in charge of the camera while I open and move the machine around.. it should make for a interesting photostream. you might even catch glimpse of my other family members as well.
right now my youngest is performing the ‘how many times can I jump on the machine before daddy freaks out’ benchmark..
