@ataru_m2003: "Hi
Do you know if there's a way to flush the memory allocated for closed 
tabs?
I've seen that if I open Gmail, for example, Opera use about 50MB of 
ram (more than 100 for Greader!).
When I close Gmail tab I'd like to release that ram but it doesn't 
happen
(Opera 10.50 on Windows XP SP3)

Opera keeps pages in its 'cache' so that if you go back to the same page 
again you can see it quickly without having to fetch it all over the 
internet again.  You can adjust the cache settings in Tools - Preferences 
- Advanced - History.
If the memory space being used for a 'cache' is required for something you 
are doing right now, the operating system and other applications (including 
Opera) should co-operate to release the memory required for the current 
tasks by moving older cached data to 'virtual memory' (on the hard disc, 
usually) or deleting it altogether.  This should mean that you get the 
best use out of the available memory combined with quickest access to data 
that you are using frequently.

Why should it release the memory?
1. If you won't open the site again the memory will be transferred to the 
pagefile and never seen again. So no problem wil concurrent pagefile-
access.
2. If you open the site again after a while, accessing the pagefile and 
getting all the ready parsed and processed data is still faster than 
accessing the local disc cache and it is also still faster than getting 
all the stuff again from the network.

I see 950MB of memory taken by Opera. And I've a single tab open.
I've an old pc with 1Gb of ram, I must release memory if unused!
yes I know but I want to choose :-)
thanks

Do you have a SWAP file? How much of that 950MB of memory is actively
residing in the primary memory? If you minimize Opera and don't use
it, but use other applications, are they slow and/or do they not
receive any active memory?
