* Fixed a bug in the GC that caused performance to degrade when
...
ik_alloc extends the heap (by 128KB) and the heap size remains set
to that value (causing more frequent GCs than usual). Now, after
ik_collect, if the heapsize is less than 4MB, it's extended to
4MB (minimum).

...
* Performance gains for making a hash table of 10,000,000 elements
are:
Before: 47secs Now: 17secs.

non-allocating tconc_add procedure.

41e1859b2b
* Fized a bug in the collector that caused tconc pages to never get
...
deallocated. Tconc pages are now allocated from generation 1.
2007-06-29 01:32:16 +03:00

819a3ca1c1
* bug in collector causing dirty bits for code objects with younger reloc

of | when computing the dirty pattern.

* fixed bug in handling tcbuckets.
...
Summary of the bug:
if ik_alloc is called during gc, and if it causes a heap
overflow, then the pages are deallocated before returning to
scheme.
2007-01-19 18:13:44 -05:00

gc has tcbucket_size=16
compile allocates tcbucket_size=24
