Hello, after setting up the latest snapshot, i was caught off guard as all my numbers were off (and usually it's better than a swiss clock). So, i've double checked, stripped some cruft from compiler command line and pitted various snapshots (20050410, 20050424, 20050501) vs 20050508 in my app.
Now i can say without doubt that on x86-64 linux, on a k8, i reliably get between >3% (rendering path, mostly vectorized SSE) and >5% (kd-tree compiler, branchy & memory heavy code) performance boost. Without touching a single line of code. I don't know, yet, who's the unsung hero i should thank or what he/she did, or if that result can be correlated in any other benchmark, but that won't stop me to send my warmest kudos his/her way. Feel free to fill in the blanks :) Regards.
