Hello Friends,

We have a single threaded application which is restricted by CPU usage even though there are multiple CPUs on the server, hence leading to significant performance issues. Is it possible to merge / combine multiple CPUs at OS level so it appear as a single CPU for the application? (6 Replies)

syncer
SYNCER(4) BSD Kernel Interfaces Manual SYNCER(4)NAME
syncer -- file system synchronizer kernel process
SYNOPSIS
syncer
DESCRIPTION
The syncer kernel process helps protect the integrity of disk volumes by flushing volatile cached file system data to disk.
The kernel places all vnode(9)'s in a number of queues. The syncer process works through the queues in a round-robin fashion, usually pro-
cessing one queue per second. For each vnode(9) on that queue, the syncer process forces a write out to disk of its dirty buffers.
The usual delay between the time buffers are dirtied and the time they are synced is controlled by the following sysctl(8) tunable variables:
Variable Default Description
kern.filedelay 30 time to delay syncing files
kern.dirdelay 29 time to delay syncing directories
kern.metadelay 28 time to delay syncing metadata
SEE ALSO sync(2), fsck(8), sync(8), sysctl(8)HISTORY
The syncer process is a descendant of the 'update' command, which appeared in Version 6 AT&T UNIX, and was usually started by /etc/rc when
the system went multi-user. A kernel initiated 'update' process first appeared in FreeBSD 2.0.
BUGS
It is possible on some systems that a sync(2) occurring simultaneously with a crash may cause file system damage. See fsck(8).
