lots more performance improvements to status scripts:
* battery:
from: 0m11.056s, 0m0.270s, 0m0.810s
to__: 0m0.873s, 0m0.370s, 0m0.260s
* cpu_temp:
from: 0m2.727s, 0m0.200s, 0m0.340s
to__: 0m1.049s, 0m0.220s, 0m0.450s
* date:
from: 0m2.675s, 0m0.110s, 0m0.280s
to__: 0m1.413s, 0m0.100s, 0m0.180s
* disk:
from: 0m7.462s, 0m0.200s, 0m0.360s
to__: 0m2.000s, 0m0.150s, 0m0.280s
note: output removed a trailing space
* fan_speed:
from: 0m3.671s, 0m0.150s, 0m0.230s
to__: 0m0.677s, 0m0.180s, 0m0.220s
* ip_address:
from: 0m3.764s, 0m0.220s, 0m0.400s
to__: 0m3.314s, 0m0.220s, 0m0.420s
notes:'
* removed 1 fork in ipv4 route, 2 forks in ipv6 route
results above are with IPV6="". I do not have an explanation
for the increase in sys time on this.
* mem_available:
from: 0m4.393s, 0m0.250s, 0m0.380s
to__: 0m0.304s, 0m0.150s, 0m0.150s
* mem_used:
from: 0m1.997s, 0m0.040s, 0m0.260s
to__: 0m0.308s, 0m0.130s, 0m0.160s
notes:
* there is a 2 to 3x growth in user cpu time here.
that is primarily due to 'read'ing /proc/meminfo
however, coupled with the reduction in sys time, we're
about even and wallclock is ~ 1/6th.
* raid:
from: 0m2.842s, 0m0.130s, 0m0.390s
to__: 0m0.084s, 0m0.070s, 0m0.010s
notes:
* if /proc/mdstat was large, 'read'ing it could be slower than using grep.
this result is on my laptop where it is empty
* release:
from: 0m0.126s, 0m0.050s, 0m0.060s
to__: 0m0.158s, 0m0.050s, 0m0.100s
notes:
* there is no real difference if DISTRO is set. if DISTRO is not set,
it looks more like:
from: 0m3.506s, 0m0.140s, 0m0.330s
to__: 0m0.158s, 0m0.080s, 0m0.070s
* swap:
from: 0m7.071s, 0m0.150s, 0m0.360s
to__: 0m0.473s, 0m0.280s, 0m0.150s
notes:
* This is hand-hacked a bit, because on my system I have swap, but
the percentage used was '0' in both cases. So, I commented out
the line that returns/exits if 'f == 0'.
* updates_available:
very minimal changes, only 'which' -> 'command -v' and
2 removals of 'tail -n 1'
