Hello,

Well, reference counting adds an overhead on all pointer handling
operations, as well as additional memory (and thus cache) use. I made
this explicit with some profiling some time ago.

That's said, David Allouche tried a long time ago to add Boehm GC to
TeXmacs but this operation failed to add any performance improvement
(memory use was increased by a factor of 1.5 or 2). But maybe Stijn and
Niels can add a more efficient GC?

Yours,
david
