Hi all, I just built a new Intel Xeon FreeBSD 6.1 server with 14Gb of RAM. I started digging into PAE so that we could actually make use of the high memory in this box, and I've run into a rather vexing issue. The handbook says:
"Some system tunables determine memory resource usage by the amount of available physical memory. Such tunables can unnecessarily over-allocate due to the large memory nature of a PAE system. One such example is the kern.maxvnodes sysctl, which controls the maximum number of vnodes allowed in the kernel. It is advised to adjust this and other such tunables to a reasonable value." That's really good to know. Unfortunately, nobody seems to have written down WHICH tunables need to be adjusted besides the one mentioned above, nor is there any information on what "reasonable value" means! Can anyone point me at a resource for more information on this? Regards, Paul Lathrop
