Hopefully this question isn't too dumb. I'm wondering how expensive (system resource, and bandwidth wise) a ping is. If I have a small embedded linux device that has very limited ram, cpu, and bandwidth would it be bad to start a ping command and have it continue running for days?
I'm trying to figure out how to minimize the impact. Looking at the options for ping it looks like I can specify the size. Should I do that to make it smaller? Is there anything else I can do to make it smaller? I need it to run but I don't want it to have any negative impact on ram, cpu, or bandwidth (performance in any way).
In my testing I haven't observed any difference in ram or cpu with it running. I haven't tested network speed very thoroughly but I haven't noticed anything there either. Thoughts?
