The load time is because of the magnets. Each magnet in Poser is treated like three extra bodyparts (mag, base, and zone). Without morphs, magnets are 55% of the V4 cr2. Magnets are very memory intensive.

Linear parts are faster than branched parts. Basically the hip, chest and hand are the slowest parts because they have children brancing off them. Arms and legs respond faster because they are a straight chain.. 1,2,3.

And expamly of this is.
Say you have a snake with 100 linear segments.
And then say you also have a spider with 99 legs off one body.

The snake would be fast. The spider would grind poser to a halt. Magnets and all their parts are like those spider legs creating more branches.

All those overlapping zones and their effects with each other and the mesh uses a lot of memory. It it sort of like erc; taing a decent idea but way overdoing it until it is a nightmare. 

There is a time and place for magnets. And a time and place for erc, but both are are among the highest users of memory in Poser. They should be used in small doses.
