[opensuse] Tumbleweed speed
I have an old laptop (acer something - its my daughter's old one) that had the root file system die. It was up-to-date when this happened. So I decided to reinstall Tumbleweed. Luckily the /home partition was ok, so I just let it be. There is nothing important on this computer. It mainly contains a checkout of our current subversion source repository. The install is the same as before except that it i the latest install image, and I disabled CPU mitigations. Same file systems (btrfs for / and xfs for /home). I am fairly certain that all is set up the same: installation defaults. Unless I am imagining things, it is much faster than before the OS reinstall. I can't believe that the CPU mitigations make such a noticeable difference. Could it be other install defaults that have changed since the previous install (maybe 2 years ago)? The CPU is an Intel(R) Core(TM) i3. /proc/cpuinfo says: bugs : cpu_meltdown spectre_v1 spectre_v2 spec_store_bypass l1tf mds The kernel command line is: BOOT_IMAGE=/boot/vmlinuz-5.1.5-1-default root=UUID=be03609a-b2cb-426e-875e-aa9aaacbb5ba splash=silent resume=/dev/disk/by-uuid/f03be3df-6961-406e-82a7-7bc4deb7ef9a quiet mitigations=off I guess I should be happy. And I guess that I am. But I'm also curious. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
