New Comment:
using 5.2.17 and 5.3.3
if needed I can test on newer version but it doesn't seems anything was done
about it.
the problem is still there.
it's a HUGE probleme when using IPSec VPN as the overhead can be tremendous
with
lots of small packets.
It's not a theoretical problem. for me It's a real one that affect the business
with our partner.
anything new on the subject ? Anything I can do ?

Problem still exists.
tcpdump shows during execution test example
that 'GET ...' and 'Host ...' are sent by multiple packets:

Still considering after over a year or is this fixed by now?
(should this actually be a feature request?)

It's too late for the 5.0 branch (which is in final RC stage), but it's under
consideration for the 5.1 branch.

Will a buffer be added?
------------------------------------------------------------------------

You're correct; there is no write buffering for the http
request.
