What’s holding Warp Stabilizer back?

I’m using AE Warp Stabilizer to stabilize some handheld shots (AVCHD, 50fps, 1920*1080), which btw produces excellent results.

 

I am just wondering, whats holding it back?

 

A 30 sec clip takes 6+ minutes to analyze. The media file is around 100MB, it uses less than 16GB RAM (32GB installed) and around 8-10% of the CPU?

 

It could finish in 30 secs. if using full cpu power?
