Dynamic allocation would be expensive as you would have to realloc buffers
each and everytime it runs out of space. As far as 16k length is concerned,
yes it is rarely possible that a client sends a buffer upto 16k length but
only during ssl handshake ( unless it has a very long cert chain). But,
believe me, application data could reach that level (server ->client). So be
careful when you change those max sizes.
If you are planning to have 1000 or more simultaneous ssl connections then
you might need to get some hardware accelerator. I haven't seen most of the
software servers doing that other than if you have a very high end server.

Subject: Regarding read & write buffer sizes : pls help
Hi All,
I am very new to SSL.My knowledge says ,for each
session the openssl by default sets the sizes of
init_buf(for holding handshake data),rbuf(for reading
data ),wbuf(for writing data) to 16k each.
Is there any way I can dynamically adjust the sizes
of the buffers, as and when my server receives the
data . My concern is that if 48k(3*16k) is used by a
given connection in the session, what happens if
suppose 1000 simultanious connections are handled by
the server.
If anybody has any idea, please help me. I am not
sure how correct is this my understanding.
Thanks in advance,
Rahul.
