Date: | Wed, 05 Feb 2020 11:35:54 -0000 |
Just found in gc's source code: The environment variable GC_FREE_SPACE_DIVISOR
does the same, without creating a dependency on the library and with a possibility for the user to change the value.

Setting GC_free_space_divisor to 1 decreases GC time on GUILE v2 from
2.1s to 1.75s, a 17% speedup for the Mozart horn concerto example
Don't try to tune the GUILE 1.8 GC if we are on GUILE 2.
