Immediately used 160MB upon starting the program. Firefox is lean compared to that.

  A random number like that is pretty useless. Opera has dynamic handling of RAM, so if you have a lot of it, it will use more. If you have less, it will use less. I'm guessing you have at least 1-2 GB RAM.

  By the way, claiming that Firefox is lean because it sets hard limits instead of adapting the memory usage dynamically is pretty silly...

  You can manually set the memory cache in Preferences. I figure that unused RAM is wasted RAM. If I've got 4GB of RAM and all that caching allows to browse faster (going back a page in Opera is lightening fast), then I applaud it.

    I like getting downvoted for not knowing the minutia of a program's memory handling. Thanks, people. To Osiris: Given I'm not aware of that 150+ MB being dynamic, I assume that's 150MB I'm not getting back if and when I need it. I play memory-eating video games and use VMs; 150MB for a web browser looks like a lot when you've got to trim the fat off your running processes. Does Opera reduce its memory footprint when you are low on RAM?
