@Arthur_Gonzales_III try this experiment.

- Search your most recent Roon Server log file for an entry that looks like this

```plaintext
Info: [library stats] tracks: 44132 (hidden: 6317), albums: 7843 (hidden: 1181), artists: 3982, works: 17392, performances: 24928

```

- Feed a prompt to your favorite AI chat bot that’s similar to the following (change the numbers to use the music library metadata from the Roon Server log file)

```plaintext
Roon implements the SymSpell library. Estimate how much memory would be used with maximum edit distances of 1 and 2 for a music library that has the following counts:

tracks: 44132
albums: 7843
artists: 3982
works: 17392
performances: 24928

Note that classical metadata contains significantly longer and more complex strings than pop/rock (e.g., “Symphony No. 5 in C Minor, Op. 67: I. Allegro con brio”). Assume an average term length of 38 characters.

```

**Share back with us what AI estimates the amount of memory SymSpell will use.** Please do not copy/paste the full output from the AI chat bot.

And while you’re in the Roon Server log file, can you find and share a recent line that looks this?

```plaintext
Info: [stats] 47967mb Virtual, 3750mb Physical, 1808mb Managed, 1942mb estimated Unmanaged, 0.91% of runtime in GC pauses, 13ms last GC pause duration

```

It would be helpful to see how your server’s memory usage is split between virtual, physical, unmanaged, and managed memory.
