Thanks,
What values would you suggest for NBUCKETS and MAXALLOC?
And looking at tclThreadAlloc.c, I'm not quite sure how to make the
spacing closer.

I think one difference is in the tcl version itself; the latest
versions use a fast multithreaded allocator that allocates on
average slightly more than double the amount requestes, while
earlier versions may have been more frugal. You can cut your
memory usage by a third or more by increasing the number of buckets
defined in tclThreadAlloc.c and making the spacing closer; there
will be a bit more constant overhead and the allocator would run
microscopically slower. You may also want to look into the ttrace
module which makes all the tcl interpreters lazily load their code
instead of loading everything up front which can be a significant
savings but I have had very little luck with it (I think the
openacs code does too many fancy things to work well with it).

Hi,
A couple of weeks ago I moved a number of servers to AOLserver
4.0.10 from various versions of 3.4 because of the 10^9 seconds
problem. After the move servers that were preivously using
100-120 MB of memory are now using around 300 MB to 400 MB each.
I've tried to turn off or reduce adp and fastpath caches,
reducing maxthreds to the 40's level. Stacksize is 500k. We have
used more or less the same config files, with a few changes like
the new nsopenssl configuration format.
Has anyone else had experiences with memory usage after switching
to AOLserver 4.0, and is there any easy way to reduce it?
Thanks,
Guan
