Measure¶

Case 1¶

• 8'531 files/folders (some mp3)
• Time to index : ~1s (8'000 item/s)
• Average size per indexed item : 464 bytes.
• Total size in memory : ~3.7 MB
• Speed to do a search : < 1 ms

Case 2¶

• 309'269 files/folders
• Time to index : ~30s (10'000 item/s)
• Average size per indexed item : 140 bytes. (The filenames from case 1 are surely longer and thus own more words).
• Total size in memory : ~42 MB
• Speed to do a search : < 1 ms

Conclusion¶

This algorithm is very time effective for searching or indexing but takes a lot of memory. For the moment it will be used unchanged but some space optimization must be done for the future.
