I'm working on running this experiment now and doing benchmarking of the two methods. I need to build a kernel with the timing enabled, rebuild my initrd as squashfs, recompress it (had to install the 3.4 tools first! :) and then find a way to do something other than watch it boot.
I'm fairly confident it is better, but we will see.
Unfortunately due to a hickup (using rpmbuild instead of build) and an errant typo in an RPM spec I deleted some portions of my /usr/lib directory last night, so the next step before actually doing the test, is to get a working system installed that actually compiles again and/or can get into a desktop :D
BTW your new kernel-source and kernel-default.spec seems to work okay to a degree.. I'll be using these, would that be an unfair test or do you want me to use the original? :)
No, that would be fine. My main interest is that the data set is the same, regardless of what the contents actually are. I'm not sure how to best measure the time part of it - since the initial load from disk is definitely an important part of it. Booting quickly is one of the things we do want to better. - -Jeff - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iEYEARECAAYFAklvb60ACgkQLPWxlyuTD7I3sgCfU0L1Q2W23oK1Sm5r6B5tNCwY gfoAn3Nm5kVysoNzDFw5LO05qRVUqA8F =rUAN -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org
