With DD-WRT you have to chance to speed up things a bit ;-)

[edit] General notes about Overclocking

See whatever clock frequencies your current setting is using with command

nvram get clkfreq

This will usually show two or three numbers

nvram get clkfreq
600,300,150

First number is CPU frequency, second number is DRAM frequency, third number is Backplane frequency.

By Oct 2021 it may be necessary add the command

 nvram set overclocking=600

in order to keep the high speeds after a reboot. See forum post: https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=329420


Thus the sequence to set overclocking speed may need to be:

nvram get clkfreq
nvram set clkfreq=600,300,150
nvram set overclocking=600
nvram commit

after that do a Reboot
