"Do i look fat?"
It's a trap! If we say 'No' then the bloat continues. And if we say 'Yes you're fat' she runs away crying. And the bloat still continues.
Honestly, Yes. You're still fat. But some progress has been made. Keep going. Stop when you hear the first complaint about too skinny.
Given the choice between being forced to restart my browser because it's memory use is approaching the 4GB limit of a standard 32bit process rendering it unusable, despite my having several GB free; and it being able to remain stable by expanding past 4GB I'll take the extra memory usage.
Improving memory usage so that my browser never approaches the 4gb point in the first place would be ideal; but based on my personal history I strongly expect that any such gains will continue be eaten by increasingly heavy use on my part and those of sites I visit.
Honestly, Yes. You're still fat. But some progress has been made. Keep going. Stop when you hear the first complaint about too skinny.
