Thanks for your detailed tests.
Wearing armel buildd maintainer hat, I agreei with the conclusion. 1.5x slower
decompression is small enough hit and as mentioned decompression is only a part of
package install time.
It is worth noticing that using xz by default will slow down package builds (especially
ones with huge -dbg packages, but we are already working on getting faster armel/armhf
build machines.
