Not seeing any references to the Herumi library in that document, nor 
any evaluations of the time required for pairing based cryptography in 
that document.  Relic-Toolkit is not Herumi and is supposedly markedly 
slower than Herumi

Looks like I will have to compile the libraries myself and run tests on 
them.
