Why I did it

Profiled the execution for the following cmd intfutil -c status

Before Optimization:

root@msn-2410:/home/admin# time intfutil -c status
...................
...................
real    0m1.619s
user    0m1.221s
sys     0m0.203s

root@msn-2410:/home/admin#python3 -m cProfile -s tottime /usr/local/bin/intfutil -c status
   ncalls  tottime  percall  cumtime  percall filename:lineno(function)
      124    0.007    0.000    1.318    0.011 device_info.py:353(get_platform_info)
      124    0.002    0.000    0.890    0.007 device_info.py:332(get_sonic_version_info)
      128    0.002    0.000    0.202    0.002 device_info.py:42(get_localhost_info)
      128    0.001    0.000    0.203    0.002 device_info.py:128(get_hwsku)
       62    0.000    0.000    0.014    0.000 device_info.py:449(is_chassis)

After Optimization:

root@msn-2410:/home/admin# time intfutil -c status
...................
...................
real    0m0.883s
user    0m0.622s
sys     0m0.128s

root@msn-2410:/home/admin#python3 -m cProfile -s tottime /usr/local/bin/intfutil -c status
   ncalls  tottime  percall  cumtime  percall filename:lineno(function)
      124    0.000    0.000    0.013    0.000 device_info.py:360(get_platform_info)
        1    0.000    0.000    0.009    0.009 device_info.py:336(get_sonic_version_info)
        5    0.000    0.000    0.008    0.002 device_info.py:46(get_localhost_info)
        5    0.000    0.000    0.008    0.002 device_info.py:132(get_hwsku)
       62    0.000    0.000    0.015    0.000 device_info.py:446(is_chassis)

How I did it

  1. Cached the following information:
    • get_sonic_version_info()
    • get_platform_info()
  2. None of the API exposed to the user libraries (for eg: sonic-utilities) has been modified

These methods involve reading text files or from redis. Thus, caching helped to improve the execution time

How to verify it

  • Added UT's.
  • Verified on the device

Which release branch to backport (provide reason below if selected)

  • 201811
  • 201911
  • 202006
  • 202012
  • 202106
  • 202111
  • 202205
