The swap is having a party, That is true, unfortunately. git will fly if it can fit its working set plus the kernel stat cache for your working tree in memory. And the underlying assumption is that for large trees you'll have gobs of RAM. If things don't fit, it does get rather slow... But... just to put things in perspective, how long does it take to *compile* that checkout on that same laptop. I remember reading instructions to the tune of "don't even try to compile this with less than 4GB RAM, a couple of CPUs and 12hs". Those were for the OSX build IIRC. Ah - it's moved to the general instructions: "Building OOo takes some time (approx 10-12 hours on standard desktop PC) ": http://wiki.services.openoffice.org/wiki/Building_OpenOffice.org#Starting_the_real_build So I don't think anyone working on projects the size of the kernel or OO.org is going to be happy with 1GB RAM. cheers m
