kernel log flooded with: xen_balloon: reserve_additional_memory: add_memory() failed: -17
...[3034071040 bytes]
Total system ram: 6442385408 - 6x2^30 = 65536
The memory range indicated in the log message is "Unusable memory" in
/proc/iomem:
1b4d84000-82fffffff : Unusable memory
Another point of interest is that we have multiple "identical" hardware
platforms (Dell T320) for the system running the 3.5.0-18 kernel but
only see this error on a slightly more recent system. Older systems
show in /proc/iomem that all memory is System RAM.
100000000-82fffffff : System RAM [older system BIOS 1.0]

Improving 30-40MB/sec Sequential Reads
...I'll
delve into what I've tried/tinkered with below.
The hardware on My FreeNAS machine is an Avoton C2550, 32 MB ECC RAM, 7x2TB
HDDs in raidz2 config and using a pair of SSDs as cache devices for ZFS.
The motherboard has an onboard Intel Gigabit NIC and I've recently added a
Chelsio T320 10Gbe card as well.
I've benchmarked the local disk read speed and I get around 565MB/sec
reading a file that far-exceeds the NAS' RAM.
I've also used iperf to confirm the network interfaces aren't the
bottleneck. A single instance/thread of iperf pushes 921Mb/sec over the
1Gbe li...
