New issue by tornaria on void-packages repository

https://github.com/void-linux/void-packages/issues/34849

Description:
Maybe coming from slow arithmetic in sbcl:
```

(%i1) showtime : true $
Evaluation took 0.0001 seconds (0.0000 elapsed) using 0 bytes.
(%i2) a : 10^(10^5) $
Evaluation took 0.0192 seconds (0.0200 elapsed) using 96.047 KB.
(%i3) b : a^10 $
Evaluation took 1.1198 seconds (1.1194 elapsed) using 1023.875 KB.
(%i4) b : a^20 $
Evaluation took 4.5570 seconds (4.5607 elapsed) using 2.147 MB.

```

Contrast with maxima-ecl:
```

Note: ecl compiles with gmp so that's probably where the long arithmetic comes from.
