Show us the results of "free" and "swapon -s" commands.

hi,
old thumb rule was:
swap space = 2 x size of main memory.
but this was the rule when main memory was very low.
now a days people generally have, at least in india, 256 Mb or more main memory. Hence this thumb rule no longer exists.
If you have 256 Mb of RAM, just assign 200 Mb of space to swap. You will notice even this much of swap space would never be used.
In your case also, have 200 Mb of swap.
Personally i would advice you to upgrade your main memory (RAM)

regards

I always consider the swap as "A space where my files will go when I am using all my RAM to play silly animations and other background programs like music player."

So the question I pose myself is: "how big will the biggest file I'll ever use will be?"

In other words if I work with graphics sometimes a gimp file can occupy 300 megabytes so more than that would be useful for this case.

Can this be a new rule of thumb? considering you usually know what you are going to use that system for.
