Are LG BD-RE BU40N drives just super slow?

Is it just me or are LG HL-DT-ST BD-RE BU40N drives just super slow?

 

They're slow readers, reading about twice as slow as the Pioneers I've tried.  And I'm talking just about in data folder copy operations.  NOT in terms of ripping discs.  RipLock I could understand, but these are simple folder copy and pastes of data files that are not on encrypted discs or even in folder formats like VIDEO_TS.

 

They're slow writers.  For instance on 8x DVD+RW, they spend about half the time writing at 4x.  16x BD-R only get 12x maximum, unlike in Pioneers.
