opera eats too much RAM. How to restrict it ?

You can decrease the memory usage, but you will have to give up some functionality. Try this website:

Also, I think you can turn off the feature which searches through the text in all of your visited websites whenever you type something in the address bar (I can't remember what is the config option to turn this off), then turn off stuff that you don't use (like mail, extensions, widgets, etc). Finally you can try using opera's own toolkit (instead of gtk or qt) - set opera:config#FileSelector|DialogToolkit to 4. There are probably several other tweaks that can be done. I can't remember them all.

Certain javascript-heavy sites will gobble up tons of RAM: twitter is especially horrible, and very processor-intensive on opera, as well (xxxterm uses far more RAM, actually for a single twitter window, but also an order of magnitude less processor: 1-4% as opposed to 40% for opera).

Other things, like some web-based mail sites, are also pretty dreadful; and let us leave certain video sites out of our discussion entirely (for fear of perhaps self-incrimination).

By default, the memory cache (Preferences > Advanced > History) is set to "automatic" so it'll use as much memory as you have free. And in your case, you still have plenty of memory and no swap in use, so I don't see what the problem is. It's only a bug if you run out of memory. Find a situation where Opera causes you to use the swap, otherwise it's not a bug.
