Bug#383881: pdiff functionality cpu-bound

[Yuri D'Elia <wavexx@yuv.info>]

Package: apt
Version: 0.6.45
Severity: normal

I was wondering why, since pdiff was introduced, updating takes several times
longer than before (in fact, 12 times slower when downloading just 3 pdiffs).
Apparently the system (2x300mhz x86 system) is 100% user busy on "rred" while
updating. Can someone confirm this?
