But I quite disagree on optimizations being unnecessary. They are really crucial in cutting down the modules fat that lurks around stock kernels. This is especially true for the enterprise distributions like oldish RHELs and its derivatives. Stuff like CONFIG_FB_HYPERV, CONFIG_HAVE_KVM_CPU_RELAX_INTERCEPT, etc. from optimized kconfig do help tremendously. In a long run, your VMs run stable and with lesser loads. > Those issues, I'm happy to say, are now mostly behind everyone - at least > with recent releases of the various guest OSes. > > Yes. Seeing Ubuntu provide the Joyent's suggested optimizations is really nice, though not same for every other major distro. ------------------------------------------- smartos-discuss Archives: https://www.listbox.com/member/archive/184463/=now RSS Feed: https://www.listbox.com/member/archive/rss/184463/25769125-55cfbc00 Modify Your Subscription: https://www.listbox.com/member/?member_id=25769125&id_secret=25769125-7688e9fb Powered by Listbox: http://www.listbox.com
