I am doing a number of reads with owget on individual DS18B20's and
DS2438's and not quite getting the performance I expect:
# time ./owfs/bin/
owget -s 4444 /uncached/sw3/aux/Hallway/temperature
18.9375
real 0m 0.38s
user 0m 0.00s
sys 0m 0.01s
The actual convert_t from the datasheet should take only 10ms. What
can I do to speed this up? (yes, that DS2409 port is already the
active one).
I have also noticed something similar for DS18B20 fasttemp reads which
should take 95ms:
# time ./owfs/bin/
owget -s 4444 /uncached/sw1/main/Attic/fasttemp
-1
real 0m 0.84s
user 0m 0.00s
sys 0m 0.00s
I assume this is at least partially overhead related to the owserver
comms, is there a better way to handle multiple device access with the
owshell commands? Anything I can do to speed things up otherwise?
Thanks,
