Kernel Memeory - AMD64

[Pegasus Mc Cleaft]

Hello everyone, 

 

                I was wondering if you guys could comment or give guidance
to the following question: By watching the threads here and also in the CVS
commit group, I see there has been (or will be) a change to the way the
kernel addresses memory. Specifically in its ability to use memory beyond
the 2 gig boundry? 

 

                At the moment, I have increased the limits on my box by
adding the following to the /boot/loader.conf file: 

vm.kmem_size_max="1073741824" 

vm.kmem_size="1073741824"

 

                I did this because of ZFS and its requirements for memory
(Just take a moment here to say thank you to the people involved in porting
ZFS to the BSD platform. I love it! And I use it all the time on my
machines) But with the recent changes to how the kernel addresses memory and
its limits, am I better off removing these entries and letting the kernel
grow is memory usage as needs be, or should I increase the limits further? 

 

                If the answer is application specific, one of the boxes is a
mysql server, Q6600 w/ 4 Gigs..  The other is a Q9450 w/ 8 Gigs of ram that
serves as my desktop machine (xorg, kde, kdevelop, etc) 

 

Thank you in advance for your comment,

Peg
