RE: Win2k and cygwin memory leak

 "Me too!" `8-7, well...

 I consider this be a fine-tune issue regarding Windows, this ofcourse
affects cygwin - and all other software packages that has been installed.
I'll let it be unsaid whether this should have been automated by M$ or
not... (I _do_ have an opinion... ;-)

After having read what is on this page:
> RAMpage =>

I can only say; I _DO_ agree.

 I have been running W98 (and SE) ever since I got my brand new P2@450/128MB
(it was top spec. at that time!) - I installed W2K just recently. (Now w

 The first 2-3 years it was turned on, all the time - running the first
"" projects. At least three times a week I had to restart
windows, simply because RAM was all wasted. As I later concluded - it was
vcache (i.e. disk buffering) that filled up RAM to the extent that there was
NOTHING left for application use - at this point all memory allocations lead
to EXTENSIVE swap file use.

 IMO this behaviour was/is very prominent in W98. I found a remedy though...
first running a sibling to RAMpage, then by fiddling a bit with
"system.ini" - see below.

 This little addition to the ini-file has held the machine very much more
usable, with just a little more disk-thrashing as side effect.

 I wouldn't be too surprised if there STILL is something like this left in
more recent Windows versions.
If there is a this easy remedy for them is beyond my knowledge.

 So, cgf is right here IMO.

 I have kept maxfilecache (KBytes) at 10-20% of installed RAM and chunksize
(Bytes) as high as I have considered reasonable.
   a) maxfilecache/chunksize should be a fairly high number. (better
   b) chunksize shouldn't be _too_ small. (too small -> overhead grows)

 Please note that I have NOT done any benchmarks here...
