Update November 14th, 2016: This is an old article but my recommendation to hack the NFS file still stand even given how inexpensive small SSDs are. An SSD ZIL still delivers low performance with ESXi/NFS unfortunately. We have have a dual SSD ZIL setup on this file server, and without the NFS hack we still… Read more »

Modern Intel CPUs employ a technology called TurboBoost which works in conjunction with Intel’s SpeedStep technology to temporarily overclock specific cores (sometimes at over 2x the advertised speed) when thermal and power limits allow. SpeedStep is the selective and rapid slowing down, idling and possibly even sleeping of cores which are not being used or… Read more »

Out of the box, FreeBSD’s default SNMP daemon bsnmpd(1) does not support the UCD-SNMP-MIBs which is where all the “good stuff” like CPU, disk, network and memory that us sysadmins like to monitor. Adding this module is as easy as installing the bsnmp-ucd port and doing a quick update to bsnmp’s config file: $ cd… Read more »

I also to run across this error when working with certain FreeBSD VMs (FreeBSD 7 and 8.0, 8.1). I think the vmware-guestd6 port is missing a dependency. Here is the problem: $ /usr/local/etc/rc.d/vmware-guestd start /usr/local/etc/rc.d/vmware-guestd: WARNING: failed to start vmware_guestd Not too helpful and the logs don’t show anything either. If we try to manually… Read more »
