📄 Description

…e cpu usage

  • read the CONTRIBUTING guidelines
  • raised a GitHub issue or discussed it on the projects chat beforehand
  • added unit tests
  • added integration tests
  • updated documentation if needed
  • updated CHANGELOG.md

I've been watching the cpu situation for the past few days, and I found that the cpu occasionally suddenly rises to 500%, so I used pprof to check and found that ToStringSlice causes the cpu to rise.

After optimizing it, the cpu is still rising occasionally, but not very much.

The final solution should be to use the cache to store the machine information for comparison, and modify the database data and cache information only when there are changes. I'm not familiar with it, so I haven't made the appropriate changes yet.
