Well, what about it then ? ;-)
I don't use Opera since "aptitude install opera" doesn't work, and I am
lazy, and also a bit worried to do my web browsing with a closed source
browser (which include built-in p2p "sharing" feature as I read ?).
I gave it a quick try out of curiosity (didn't like the way it drops a
file in /etc/apt/sources.list.d without displaying a blood red warning
to ask me if I was willing to accept it, seems to be a trend, google is
doing the same).
First my eyes popped out:
Tux@deblove:~$ smem -nktP [o]pera

5662 1000 /usr/lib/opera//operaplugin 148.0K 165.0K 884.0K

Then after investigating the situation it appeared that java plug-in is
loaded for no good reason in Opera and sucks up a lot of memory,
sometimes only. Here is a result when java isn't interfering :
Tux@deblove:~$ smem -nktP [o]pera
PID User Command USS PSS RSS
8222 1000 /usr/lib/opera//operaplugin 144.0K 167.0K 880.0K

7933 1000 /usr/lib/opera/opera 154.0M 155.1M 168.9M
-------------------------------------------------------------------------------
91 1 237.0M 240.6M 263.3M
Keep in mind that I didn't reset my default chromium profile, so it has
several extensions Opera doesn't have. Every "blocker" extension in
chromium was disabled though (flash and adds).
Opera is slower when loading the same tabs set, especially heavy flash
content. On the good side it showed the best behaviour when it comes to
java applet test (a secure bank login applet), but consumed crazy
amounts of memory in this situation (blame is more on Java I guess).
Chromium just fails on the java applet test, maybe due to a rejected
user agent string ?
Opera version was 10.63.6450, chromium is from experimental version
9.0.587.0~r66374-1.
System is Squeeze/Sid/experimental amd64, flash is native amd64 "square"
beta.
This is Iceweasel (experimental 3.6.12-2) on the same tabs set:
Tux@deblove:~$ smem -nktP [f]irefox
PID User Command USS PSS RSS
9203 1000 /usr/lib/iceweasel/firefox- 139.9M 145.9M 162.6M
-------------------------------------------------------------------------------
77 1 139.9M 145.9M 162.6M
If we want to do something like a debian-user-list-browser-benchmark we
should agree on a list of urls to test with, maybe 10-12 tabs should be
enough, tools and protocol. I won't give my list since it includes my
Christmas shopping, my bank, and a few controversial politicly incorrect
urls like http://wiki.debian.org/DebianArt/Themes/SpaceFun ;-) (love
what they did).
Cheers.
