[call for helpers!] Tuning for the Beaver Challenge

[Dung Patrick]

Is vm.max_proc_mmap autotune by maxusers?
If maxusers=3D0, it determine proc_mmap from RAM size?

Could you please explain the use of net.inet.tcp.tcbhashsize?

In section 2.2.3, /etc/sysctl.conf:
To our experience, it also helps to tune inode cache behavior by setting:

vfs.vmiodirenable=3D"0";  (maybe)
vfs.nameileafonly=3D"-1"

On a server with large memory, if apache 1.x is tested, maybe it is also ne=
cessary
to increase:

vm.max_proc_mmap

In section 2.2.4, /boot/loader.conf:
Do you need to increase "net.inet.tcp.tcbhashsize" ?
