As per the man page TCP(4): > fastopen.ccache_bucket_limit > The maximum number of entries in a client cook= ie > cache bucket. The default value can be tuned = with > the TCP_FASTOPEN_CCACHE_BUCKET_LIMIT_DEFAULT > kernel option or by setting > net.inet.tcp.fastopen_ccache_bucket_limit in t= he > loader(8). the `net.inet.tcp.fastopen.ccache_bucket_limit` should be able to tuned the value. Steps to repeat: ``` # echo "net.inet.tcp.fastopen.ccache_bucket_limit=3D32" >> /boot/loader.conf # reboot .... # sysctl net.inet.tcp.fastopen.ccache_bucket_limit 16 ``` Expected value: ``` # sysctl net.inet.tcp.fastopen.ccache_bucket_limit 32 ``` --=20 You are receiving this mail because: You are the assignee for the bug.=
