Hello everybody,
To test the python 2.5 garbage collector, I wrote a trivial script
allocating dummy objects of various sizes, then forgetting them in a loop.
The garbage collector seems working well, limiting the memory used.
But I've noticed a near linear slowdown of the execution : after a few
minutes - and several millions of allocated and freed objects, each
iteration take more and more time to execute.
On a related note, there have been past threads reporting that
allocating and freeing increasingly long arrays, especially of tuples
(as I remember) can take more than linearly increasing time. The
solution was to turn off gc during the allocation phase so it did not
get triggered and spend increasing long times searching for collectible
objects when there were not any.
