on LAN with running stunnel, to pass encrypted data to remote SSL clients<br />
if they are on very slow GPRS network. If server in LAN starts to transfer<br />
big amount of data to such slow remote client, stunnel is buffering data and<br />
slowly transmits them to the GPRS client. TCP Window on connection from LAN<br />
server to stunnel is big (64 - 131kB), and TCP Window on connection from<br />
stunnel to slow client is small (about 5kB). And additionally stunnel is<br />
buffering data. So, server is finishing transmission in seconds, but in fact<br />
most of data are still in buffers of stunnel. And it makes a timeout problem<br />
(server is waiting for the confirmation from client if it received all data,<br />
but time between last byte sent from server and confirmation from client<br />
could be even several minutes).<br />
<br />
So, stunnel is working in "store and forward" model. Is it possible to<br />
switch it to something like "cut through"? Or how to force stunnel to more<br />
synchronized transmission between client and server?</stunnel-users-bounces@stunnel.org></mailto:stunnel-users-request@stunnel.org?subject=subscribe></https:></mailto:stunnel-users-request@stunnel.org?subject=help></mailto:stunnel-users@stunnel.org></http:></mailto:stunnel-users-request@stunnel.org?subject=unsubscribe></https:></stunnel-users.stunnel.org></stunnel-users@stunnel.org></madgaikw@cisco.com></stunnel-users@stunnel.org></stunnel-users@stunnel.org></stunnel-users-bounces@stunnel.org></stunnel-users-bounces@stunnel.org></p>
