[openib-general] why sdp connections cost so much memory

[zhu shi song]

OS: RHEL 4.3
kernel: 2.6.9-34.ELsmp
On Server:
(0) eth0: 192.12.10.24
    ib0:  193.12.10.24
(1) sh zhuset
    ulimit -n 64000
(2)
    squid.sdp -d 10 -f squid2.conf
(I have changed squid to squid.sdp, squid.sdp is
always listening on sdp socket 3129)
On Client:
    eth0: 192.12.10.14
    ib0:  193.12.10.14
