Lightroom 4.3 sub-par copy speed from memory cards

Import copy speed of RAW files is much slower in Lightroom 4.3 than simply drag-drop copy in Finder. With USB3.0 reader and Extreme Pro card, I'm only getting under 20MB/s transfer speed in Lightroom, whereas in Finder I'm getting around 60MB/s with the same hardware.

I think this is important. Please fix this.

OSX 10.8.5
Macbook Pro Retina 2012, SSD drive
Lexar Professional USB3.0 CF+SD reader
Sandisk Extreme Pro UDMA7 (90MB/s) 16GB card

Lightroom 4.x will very likely receive no further updates. Have you tested Lightroom 5.x?
