We're not talking about "Packed Disk Primitive" right ? just plain packed prim. I opened his scene, upped the number of points to 350 000 , opened a performance Monitor, hit record and turned the blue (display/render) on. I red 32.4s on the Total Statistic. (it varies a bit, between 34s and 30s) And this doesn't include the scatter computation. My machine is a dual xeon of 2013 or 2014 at 2*6 core at 2.3Ghz 64GB ram. Not the most recent maybe ? Am I totally off ?
