Search prototype¶

directory : source:/prototypes/03_Search

Goals¶

• Search with glob pattern.
• Measure the time for searching among 50'000 files. There is always two measures to test the caching capacity of the OS.
  • A solution is to generate randomly empty files and folders and create an iso with it which will be stored in the repo.
• If time is above 1 minute for the first time and above 3 seconds for the seconds then an another solution must be found like an indexing system.
