Hi, I want to reduce boot time in my product. I disabled all unnecessary modules/libraries and scripts which get load at boot time. After this my boot time is approx 9 sec. I still want to further reduce it.
>From debugs i identified 2 places where approx 1 sec is utilized (total 2 sec). *a.* When preinit is called At *[ 3.780354] init: - preinit - *and before mounting file system at * [ 4.913811] UBIFS (ubi0:2): background thread "ubifs_bgt0_2" started, PID 104b.* When ubus daemon is called At* [ 5.828610] procd: - ubus - and *before init process is called at * [ 6.864240] procd: - init -*Attached debugs file for reference. The delay highlighted in above two locations can be reduced or not? -- Thanks & Regards, Arjav Parikh
