android - Does starting the adb shell take a lot of resources? -

i use bash script automate processes on android devices in office. call shell in script: (let ... stand amount of adb shell commands.)

#!/bin/bash  ...  adb shell stuff adb shell stuff adb shell stuff  ...  exit 

these scripts function well. have done research on sending multiple commands single instance of shell; i'm wondering if efficient can though. using lot of system resources? potentially raise issues in future when i'll running very large automation scripts using process?

starting of new sh process not take lot of time or resources. queuing multiple commands same sh instance not provide noticeable performance improvement. mindful of commands run in shell sessions. commands input not native binaries java applications take longer time start - not expect able fire multiples of per second.
