Years ago I worked in the VAX/VMS development group at Sybase where SQLServer originated. SQLServer was basically an SQL interpreter consisting of several layers of loops. The innermost loop was written in assembler for speed.
I was able to remove one (1) machine language instruction from that innermost loop. I no longer recall if this resulted in a measurable difference but I've always been proud of this.
