I've initiated the post "select() too slow".
The example I've done was a non-blocking tcp echo_server.c and how
slow it was on linux compared with cygwin.
In fact after activation oh tcp_nodelay option the times were similar.
Meanwhile I've done another test, I've added ssl on top of that
echo_server.c with similar results than on linux, with the
tcp_nodelay set, and the results are again against cygwin binary.
On cygwin is too slow. I just don't know where the problem is.
Thanks for that what was interesting with scp was direction had
a large impact on performance.
On FreeBSD from Cygwin -> FreeBSD 700KB/s
On Cygwin from Cygwin -> FreeBSD 1.2MB/s
On FreeBSD from FreeBSD -> Cygwin 6.4MB/s
So there is definitely performance to be gained. I had a similar
problem with a basic perl FTP script uploading from Cygwin to
a FreeBSD machine and there simply setting the block size
to 8K fixed the issue. Note: From FreeBSD -> FreeBSD the
script didn't require said fix but it didn't effect it either. This
may be something to look at as well.
