Prefetch is evil and is disabled by default in illumos based
distributions (in newer versions it is enabled for scrubs since these
are sequential in nature and can get a performance boost). I'm talking
about the Adaptive Replacement Cache (ARC). This uses various metrics
such as lru to determ
The other question I forgot to ask...
With zfs and 4G RAM running, the prefetch is automatically
disabled. Did you make the loader.conf change to enable prefetch
caching anyway?
Thanks.

You are doing what I want to do. Which RAMdisk program are you
running? Do you have a script that flushes the RAMdisk contents to
disk periodically, so the info on the hard disk doesn't get too
stale between reboots?
Could you share your init Script(s) wi
You actually answered another question I had as well. I noticed in
my latest server-build, that the 'top' command shows an additional
line that I'd not seen on the previous server:
Mem: 36M Active, 29M Inact, 206M Wired, 5647M Free
ARC: 59M Total, 12M MFU, 45

We don't greylist. But all external (receiving only) Frontend Servers Mailers
are running in Ramdisks. This gives extremely good results espacially when
receiving extreme high amounts of incoming Mails..
If rebooting
Well sort of...
With ZFS this happens automatically because the file information is
cached in the ARC RAM unless forced out. I'm currently running a 91%
cache hit rate on this server which runs file, web, streaming, and mail
services. It's running OpenIndiana (hipster) and has 4G RAM with 4
