Firebird speed RUBY vs DELPHI vs .NET

I did some comparitions selecting 1000, 10000 and 100000 with Ruby Fb gem, Delphi Fibplus and the FB .NET driver, here is the result:

ROWS	RUBY	DELPHI	.NET
1000	0.12	0.47	0.09
10000	0.94	0.48	0.53
100000	10.95	3.79	5.53

The results are on milliseconds, the table is from a production database with 40 fields and about 3 million records, as you can see, native code is still the king, .NET result are quite good, but Ruby is quite dissapointing handling lots of data.
