vxfs_ifree_timelag - VxFS inode free time lag (specifies the minimum
time to be spent on a freelist)
SYNOPSIS [Toc] [Back]

DESCRIPTION [Toc] [Back]
In VxFS, the unused inodes are put on a freelist. The memory space for
this unused inode is freed if it stays on the freelist for a specified
amount of time. The vxfs_ifree_timelag tunable specifies the minimum
amount of time should spend on a freelist before its memory space is
freed. The time is specified in seconds.
vxfs_ifree_timelag is a dynamic tunable. Any changes to
vxfs_ifree_timelag take effect immediately.
EXAMPLES [Toc] [Back]
Change the value of vxfs_ifree_timelag to 2400 seconds:
# kctune -s vxfs_ifree_timelag=2400
WARNING [Toc] [Back]
Incorrect tuning of vxfs_ifree_timelag may adversely affect system
performance.
All HP-UX kernel tunable parameters are release specific. This
parameter may be removed or its meaning may change in the future
releases of HP-UX.
Installation of optional kernel software, from HP or other vendors,
may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or recommended
values. For information about the effects of installation on tunable
values, consult the documentation for the kernel software being
installed. For information about optional kernel software that was
factory installed on your system, see HP-UX Release Notes at
http://docs.hp.com.
