Subject: [PATCH] kernel: ct: size the hashtable more adequately
|
|
|
|
To set the default size of the connection tracking hash table, a divider of
|
|
16384 becomes inadequate for a router handling lots of connections. Divide by
|
|
2048 instead, making the default size scale better with the available RAM.
