Linux in Exile has refined the empirical test of which operating system boots more often. Details and discussion here.
Of course, it also matters that Windows requires constant rebooting for the purpose of routine maintanance, while Linux does not, so the total ‘boot wait’ time (TBWT) for the two systems is so different that they really can’t be compared at all.
Meanwhile, …the new Linux Kernel (2.6.10) has faster boot time and will run faster than the previous Kernel.
Thanks to the already implemented fastboot patches, the new Kernel 2.6.30 has the ability to recognize hard disks simultaneously and therefore significantly quicker. Ext 4 operates more securely, and Ext 3 increases performance.
Kernel 2.6.30 has arrived, and along with Tux as the old new mascot, is accompanied by an assortment of modifications to the new data system Ext 4.
Those of you who have been following the ext4 maneno will want to read the whole story here at Linux Magazine.
