So now I know the requirement. I expect 300 connections per second and each 
connection keep for 200 
seconds. So my value on the connection hash table should be 16 (2^16=65536)

Now.. how do I set this value without recompiling the kernel. The way I'm doing 
is that how ipvsadm 
.rpm package patch the kernel to support lvs. The default .rpm package's hash 
table value is 4096 
and I need this to alter to 65536 by using src.rpm package. There is a kernel 
patch 
ipvsadm-1.24-kernhdr-1.2.0.path where I can change the default value:

+#ifndef CONFIG_IP_VS_TAB_BITS
+#define CONFIG_IP_VS_TAB_BITS   12
+#endif

to

+#ifndef CONFIG_IP_VS_TAB_BITS
+#define CONFIG_IP_VS_TAB_BITS   16
+#endif

and build the .rpm package. There is no luck on this method. Do I really need 
to re-compile the 
kernel..?

Please help
Regards
Hirantha
