Thanks. I find the answer of this question in LVS_2.2.13-HOWTO, blush. :)
these days I am too busy to read the HOWTO, I will check it out tomorrow.
and the HOWTO said:
"The hash table is used to speed up the connection lookup. The connection
entry is used keep state so that packets belongs to a connection from
the client will be sent to the server previously allocated for the
connection. The default number of connections (== number of entries
in hash table) is 2^12. This can be configured when building the kernel
Makefile."
I find some files about this:
include/net/ip_vs.h
net/ipv4/ip_masq.c
net/ipv4/ip_vs.c
but I cannot find '2^12' and where can I change this parameter.
Suppose there are 6000 connections to Director at the same, and the ppc is
default,
what should this parameter be set to ?
and what is the upper limit of this parameter?
thanks again.
ttao.
