Ok, so save the project, stop k3b, issue the above command in bash and
restart k3b from that bash session?
Ok, but:
[root at coyote ~]# limit memorylocked unlimited
-bash: limit: command not found
So I'm puzzled to say the least :(
But this worked I think:
[root at coyote ~]# ulimit -l unlimited
[root at coyote ~]#
Restart k3b, reload project. Burn speed is AUTO and its trying to do a
16.4x burn on a 4x disk! The buffer fifo is mostly empty. But its done
about 600 megs in 3:30 so as the disk is wasted in any event, I'll let it
finish & verify before I force a lower burn speed. Interesting
experiment in other words. I've had k3b eat my lunch and take the
machine down when a burn abort was attempted.
Darn, I just remembered I had started 'smartctl -t long' on the src drive
too, so that certainly isn't helping the read speed I'd imagine.
It has 15 reported errors according to smartctl -a, so I'd imagine we
should bin that drive, (smartd was sending me emails about its problems)
but I was testing anyway. Dumb, duh, alzhiemers, etc :(
Humm, later, its burnt and verifying, and I can read, dimly as its
ghosted, that the burn speed was 3.8x, much more like it. But the
highest I ever saw the buffer fifo was 5% after the burn actually
started.
Amazing, k3b is playing the charge. Repeat for the rest of it.
Question: Is this 'ulimit -l unlimited' system-wide or only for this
particular invocation/session of bash?
