The Sun T2000

Niagara vs ftp.heanet.ie Showdown

“ftp.heanet.ie is one of the single busiest webservers in the world. We handle many millions of downloads per day, but unusually for a high-demand site, we do it all from one machine.” […] “Bottom line, the T2000 was able to handle over 3 times the number of transactions per-second and about 60% more concurrent downloads than the current ftp.heanet.ie machine can (a dual Itanium with 32Gb of memory) running identical software.”

Anandtechs first review of the T2000.

The Sun T1000/T2000 seems to be an awesome server, I’d love to see how Ruby on Rails-applications perform in it.

Don’t forget to read some about the ftp.heanet.ie server too, interesting setup with a heavy loaded Apache installation.
