Some benchmarks :

Alenka : Pentium E5200 (2 cores), 4 GB of RAM, 1x2TB hard drive , NVidia GTX 260
Current Top #10 TPC-H 300GB non-clustered performance result : MS SQL Server 2005 : Hitachi BladeSymphony (8 CPU/8 Cores), 128 GB of RAM, 290x36GB 15K rpm drives
Current Top #7 TPC-H 300GB non-clustered performance result : MS SQL Server 2005 : HP ProLiant DL585 G2 (4 CPU/8 Cores), 128 GB of RAM, 200x36GB 15K rpm drives

Time of Q1 of TPC-H Scale Factor 300 :

Alenka Top#10 Top#7
178s 485s 309s

Alenka is a pretty much work in progress so please be careful if you use it on a production data :-)
