I build the whole thing, daily. from scratch, without ccache, with something that isn't too far from a make allmodconfig, on a half dozen different architectures (with multiple builds for each sometimes - 586/686, various ppc flavours etc). Our build system spits out 2.6 kernel RPMs not noticably slower their 2.4 counterparts, which were also pretty close to a make allmodconfig. If the builds took _twice_ as long, I would've been shouting from the rooftops long ago. The factors you mention make it sound like something is very very wrong somewhere, but there's no clear sign why this is affecting you so badly. Maybe you should try profiling things and find out where the additional time is being spent. > building stuff on 2.4.x. When I went to build stuff using > the new build procedure I was shocked.

How much RAM do you have ? And are you using the same version of gcc for both 2.4 and 2.6 builds ?
