poor download rates with sony alpha 7s

[leelol]

Hello gphoto team,

I just updated to gphoto2 2.5.11

But sadly the caturing time on my system rises from 2 seconds (v 2.5.10) to 5 seconds (v2.5.11 )

I have tested both calling gphoto directly:
gphoto2 --capture-image-and-download --no-keep --filename myfilename.jpg --force-overwrite

Or calling the capture from the gphoto shell:
capture-image-and-download

My system is:
Mac, OSX 10.10.5
Sony Alpha 7S

Camera Settings
"USB Connection“ : PC Remote
"USB LUN Setting“ : Single

gphoto2 2.5.11 clang, popt(m), no exif, no cdk, no aa, jpeg, readline
libgphoto2 2.5.11 all camlibs, clang, ltdl, no EXIF
libgphoto2_port 0.12.0 clang, ltdl, USB, serial without locking
