*What did you do?*
I encountered a memory problem with the GO program, see here for
details.(https://stackoverflow.com/questions/71994609/memory-footprint-of-the-same-program-varies-greatly-in-two-similar-environments)
In order to simplify the analysis, I wrote a simple program to test.
```go
package main
import (
"time"
)
func main() {
time.Sleep(60*time.Second)
}
```
- I compiled it into binary file on a linux host `host1` with kernel
4.18. Then I run it on `host1` and the process takes up close to 5MB RSS.
- I then copy the binary file to another host `host2` with kernel 4.18.
I also ran it on `host2`, but this time the process took up less than 1MB
RSS.
- I repeated the test many times and observed the same thing.
```
$ uname -a
Linux host1 4.18.0 #1 SMP Wed Nov 10 20:46:19 CST 2021 x86_64 x86_64 x86_64
GNU/Linux
$ uname -a
Linux host2 4.18.0 #1 SMP Fri May 8 10:59:10 UTC 2021 x86_64 x86_64 x86_64
GNU/Linux
```
Why is memory footprint of the same program in similar environments so
different? What factors might be contributing to this problem?
*What did you expect to see?*
I would expect to see the memory footprint of the same program in similar
environments be close. I look forward to your answers. Thank you very much.
