Again:
That does say nothing except for that Opera tends to be quite greedy
regarding allocating virtual address space.
But then on a 64 Bit system there is plenty of it. On this ThinkPad T520
with Sandybridge i5 Dualcore:
martin@merkaba:~> grep VmallocTotal /proc/meminfo
VmallocTotal: 34359738367 kB
If I am not completely mistaken thats 32768 GiB.
Look for RSS or resident set size as virtual address space is just the
kernels way to play poker with applications.
Its the physically used memory that counts.
