Emmanuel Lecharny updated DIR-108:

    Attachment: Chunked.png

I've done some tests based on the 0.9 Apache DS and the same version with the patch I've attached
in a previous comment. Here are both screenshot of the same JMeter run : the un-chunked version
has a 5 x times better througput than the original version (only one thread requestiong 1000
times the same thing...).

I agree with Alex and David. Rewritting the whole codec will certainly improve performance
a lot. Let's do it, and do it now ! I think that the encoding part is the most important one
as it's the one that send search results.

> PDU that are created by ApacheDS server are sent back in small chunk. A lot of IP packets
are necessary to reconstruct the LDAP message : typically, each TLV is sent as a TCP packet.
