kernel26 in [testing] 40 % larger than prev. build

The new line in the PKGBUILD for the -3 and -4 series compresses the modules via gzip which according to the comment saves 100 MB of space.  I don't understand but somehow the size of the compiled package is about 40 % larger larger now:

34.8 MB -- kernel26-2.6.37-3-x86_64.pkg.tar.xz

Compared to

25.0 MB -- kernel26-2.6.37-2-x86_64.pkg.tar.xz

If the modules are compressed shouldn't that equate to a reduction in package size as well as installed size?  Am I missing something?

xz can probably not compress gzip compressed data very well resulting in this increase.

A little counterintuitive but makes sense... at least the installed package is smaller.  Thanks for the reply.
