Unsure what the specifics are for your system but I'd recommend attempting to install 'bootchart' (should be as simple as apt-get install boothart) and seeing what's using most of the time during boot, so you can figure out what it is you want to optimise. Another generally good idea would be to

Hi, I am working to reduce boot up time of debian on a20 processor. I came across a website which states Avoiding Ramfs can speed up boot time. what is the procedure to do so and will that be helpful to a great extent ? Thanks Divya
