Basically I need to gather some statistical data about other computers.
Download it from here.http://speedtestjavaold.irc4.net/ It needs -Xmx1000M switch so be prepared. It outputs a file out2.txt where is all info.
As the name suggest it’s old real live testing program, it might be somewhat outdated. Translated amount of tests is rather low so it could end under 5 minutes on Celeron 300 MHz.
Damned internet protocol dislikes spaces in the name.

Think my system is hurting because your testcase appears to need > 700MB of memory.

Interesting results.
I nearly missed obvious optimalization of moving vector calculation into more than one threads. It looks like Sparc could nearly nail P4HT.
It’s interesting the AMD on die memory controller could do this speed up of memory allocation.
I suspect EgonOlsen’s computer is running Windoze XP, right? If thread finish 500 would be encountered on a repeated run, Windoze XP is hendayo system.
The strange thing is that stat about HD seek. Could it be because of fragmentation of HD?
BTW how ugly it looked for other programs when this little test started? Did it cause sound delays, or mouse drag?
re NVaidya
It wasn’t because of your system, this program needs more than 700 MB memory. It was funny test when It was attempted on computer with 200 MB RAM (and 1.2 GB of swap file) installed.
Ok lets run this on a mondern SPARC instead of a 10 year old one
