Hi,
I have been always using Opera with looots of opened tabs.
However, recently it seemed to consume more CPU than usually it did...
I tried to reduce number of tabs to the most needed - about 15 (my God,
now I can see the favicons, and even a part of title!!!! ;), but opera
still consumes 20-30% of CPU.
None of those opened websites feature Flash, even no animated GIFs are
present, and all sites are quite small - no tons of large images or
something. My CPU is not a bleeding edge, but also not a piece of crap
stolen from museum: Pentium(R) Dual-Core CPU E5200 @ 2.50GHz.
I have checked what actually takes so much CPU - and launched the strace
for the PID of Opera. And it seems that opera constantly tries to get some
resources in order to check the time. Most probably it is caused by some
specific configuration of my kernel - however, it definitely should not
react like this.
Here is the part of strace, which is constantly repeated (with various
numeber of clock_gettime between select-read sequence):
clock_gettime(CLOCK_MONOTONIC, {618015, 817279354}) = 0
clock_gettime(CLOCK_MONOTONIC, {618015, 817300132}) = 0
clock_gettime(CLOCK_MONOTONIC, {618015, 817320764}) = 0
clock_gettime(CLOCK_MONOTONIC, {618015, 817341422}) = 0
clock_gettime(CLOCK_MONOTONIC, {618015, 817361865}) = 0
clock_gettime(CLOCK_MONOTONIC, {618015, 817382223}) = 0
clock_gettime(CLOCK_MONOTONIC, {618015, 817402735}) = 0
clock_gettime(CLOCK_MONOTONIC, {618015, 817423118}) = 0
clock_gettime(CLOCK_MONOTONIC, {618015, 817443611}) = 0
clock_gettime(CLOCK_MONOTONIC, {618015, 817464009}) = 0
select(78, [3 74 75 76 77], [], [3 74 75 76 77], {0, 0}) = 0 (Timeout)
read(3, 0x8f42e10, 4096) = -1 EAGAIN (Resource temporarily
unavailable)
Any possibility to repair this? :)
