Thus LVS will have to do on average n/2 traversals instead of n/2^(IP_VS_CONN_TAB_BITS+1) traversals. The real effect is to amplify traversal times by 2^IP_VS_CONN_TAB_BITS. WebTo provide some statistics, I did an oprofile run on an 2.6.31 kernel, with both the default 4096 table size, and the same kernel recompiled with IP_VS_CONN_TAB_BITS set to 18 (218 = 262144 entries).
