Yes ! I created this little test which I ran on my Windows laptop :
https://gist.github.com/Dwarfobserver/f30d2de442d05a0b8e74fcf91eba53f2

So, the aos approach took 12s, the soa 7.5s and the hybrid 1.65s.
Of course, I can change a lot on your compiler, CPU, memory capabilities and use case.

Have you got any performance data from sample programs to indicate what sort of performance increase might be achieved?

Scientific computing is another area where such layouts are really important. Maybe worth mentioning the last layout type is often called Array-Of-Structure-Of-Arrays (AOSOA)?
