Hello, I recently downloaded vanilla kernel sources from www.kernel.org. I compiled the sources on my host system to do a performance test, also using "time".
My CPU is an Intel centrino core duo at 2Ghz. To compile my vanilla testing kernel I did: make defconfig time make -j3 Results: real: 1m54,535s user: 3m16,800s sys: 0m18,920s Very good... ;) I started UML and i did the same thing.. compiling a vanilla kernel with the same config file.. uml # make defconfig uml # time make -j3 These are the results!!!! real 8m45.393s user 2m53.770s sys 0m30.310s O_O It's simply incredible!!!! Why performances decrease in this way???? UML is in skas3 mode. Command line is "linux ubd0=rootfs.debian ubd1=swapfs.debian eth0=tuntap,,,192.168.1.110 mem=1000M" Please, tell me what can I do... That time is to high!!! Thanks, Flavio. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
