@cmdr

Part 3 will attempt to provide some reasoning for how much swap space is necessary, including an argument for “Is any necessary?”. Check back soon for the final installment of the series and hopefully that will answer your question!

Nice article.
Do we realy need swap if we have 2G of memory.

I an using window (shame on me) and it seems that the whole memory is never use. However the system seems to use hard drive all the time.

Just to make a point of comment, the default in-kernel hibernate doesn’t save the entire contents of memory, it performs a kind of flush and saves just what it deems absolutely necessary.

This is why when you return from a hibernate, even though GNU/linux has returned you to your environment that the hard disk often continues to read things back into cache memory giving the impression of a sluggish machine for a while until things have re-cached.

I believe tux-on-ice is capable/dose save all the cache information as well however it will significantly increase the hibernate and resume from hibernate process.
