*tl;dr* Is it sensible to use zfs on top of cgd or are there drawbacks w.r.t.
zfs expecting raw I/O?
(Too many) details follow.
I plan to re-purpose a circa 2012 Supermicro server for a cheap home NAS. It
comes with an LSI MegaRAID

It's Turbo Boost mode, which mostly says that the CPU runs at xxx0 MHz
but may increase that as long as the thermal limits aren't reached.
You use it as an additional ACPI p-state with an unspecified

That says that estd uses sysctl machdep.cpu.frequency.* to

You're right about this: Turbo Boost seems to go from the Processor Base
Frequency to Max Turbo

Intel says (same Turbo Boost 2.0 page):
Maximum turbo frequency indicates the highest possible

I didn't use quite as many layers, but I tested this some time back and
did not have any particular problems with

When the processor is operating below these limits and the user's
workload demands additional performance, the processor frequency will
dynamically increase until the upper limit of frequency is reached.
But boost only scales up from the top

Ah thats good info that I DIDN'T know. Sadly all my BSD hardware is from the

core gen 6 and mine is gen5. So in my case I really do need estd :(

I also use estd to dymamically throttle down the cpu freqency when the

From what nia@ tells me (and this is also in the guide:
Hi Greg,
Thanks for the suggestion. I'm still doing the backup but will come back with
the outcome.
Best regards,
