[OpenWrt-Devel] Boot Time Reduction

[Arjav Parikh]

Hi,

I have disabled many core-utils as it was not being used and awk was part
of it.
Target device is IPQ8064. Whatever I could disable through menuconfig &
kernel_menuconfig has been done. Now as mentioned in previous mail only at
that two locations I see some process consuming lot of time.
Is it possible to reduce the time consumed by the process?
