Different speed of ARMv6 and ARMv7 Linux images - Raspberry Pi Forums
i've made 2 sd cards pi² :
a) 1 contains debian based raspbian has own armv7 compiled 4.x kernel, plus armv6 compiled packages compatible pi¹ , pi².
b) other card contains ubuntu 15.04 based "ubuntu mate pi²" (downloadable 3rd party image per raspberry.org's download page) has armv7 compiled 3.x kernel (plus raspbian pi drivers without james' hw mouse pointer), plus ubuntu's armv7 compiled packages running on pi².
(on both cards apt-get installed gtk based xfce desktop (the xubuntu desktop on ubuntu image), that's not important point.)
surprise many armv7 compiled packages run noticeably smoother armv6 compiled equivalents. no benchmarks, user experience desktop , "fat" applications firefox, thunderbird, or animated ones gweled, , on.
naturally, say, since armv7 has quite improvements on armv6. however, didn't know they're visible non-specialised standard applications.
other users have similar experiences armv7 compiled images?
if so, has made (or thought about) raspbian version compiled against armv7 pi² ?

there many more things consider, not if system compiled armv7:
compiler version has been used (newer version may produce better code).
how many "fixes" or patches applied gui? since foundation started modify lxde environment "simpler usage", has become slower (and needs longer start). comparison: use simple "desktop" consisting of openbox, tint2 (taskbar) , kweb browser. starts within 2 seconds commend line , includes starting xorg well. simple programs leafpad or lxterminal need less second start. (my root fs on hdd).
i've compiled programs optimized armv7 code including neon. software lots of floating point computation profit it.
