Hi,
the formula for CYGPKG_NET_MEM_USAGE in freebsd_net.cdl
(256*1024)+(CYGPKG_NET_MAXSOCKETS*1024)
is IMHO completely bogus.
First, from my debugging it looks like the stack allocates
1352 bytes per socket:
- 176 for socket
- 280 for UDP
- 616 for TCP
- 280 for raw
Second, these things are allocated from an area of
CYGPKG_NET_MEMPOOL_SIZE, which is CYGPKG_NET_MEM_USAGE/4.
I don't understand the BSD stack enough to know what exactly
can be allocated and from where, but this is surely wrong -
the pool size expands 256 bytes per additional socket,
whereas it should be 1352 bytes per socket.
Anyone already tried to find the correct way of counting?
Regards
