General Discussion / I can smell 2.4!
« on: September 16, 2017, 10:20:41 am »
Was stuck in the 90s, then one day out of the blue, it dropped into the 60s, slowly broke into the 50s, but went back up to the 60s and held. Now it's suddenly down to 14 bugs opened! AT this rate, 2.4 will be out before 2.3.4_2 .

11.1 is released now. Just noticed it now supports the compressed ARC feature. this affects both ARC and L2ARC, if I remember correctly.

General Discussion / FreeBSD Murmur3 and xxHash
« on: June 18, 2017, 01:24:41 pm »
I've been doing some research on fast non-crypto hash algorithms at work and have found that xxHash32/64 are pretty much considered the goto when you need 64bit or smaller results. I remembered that pfSense 2.2 or some other recent version, Incorporated a change a change to the FreeBSD network stack to use Murmur3 and gained something like 3%-12% performance increase for packet forwarding.

Is there a reason why xxHash is not being used since it's about 2-3x faster at hashing, depending on the combination of arch and algorithm?

This new feature caught my attention "Directives and Streams".

General Discussion / AMD Ryzen pfSense
« on: May 14, 2017, 01:14:15 pm »
I use a Haswell i5 3.2ghz for my pfSense box, but I wonder how a Ryzen, possibly a single module (Ryzen 5 1500) version would perform.

General Discussion / New prices
« on: April 15, 2017, 10:57:48 am »
Seems my ISP rolled out new prices

70/70 $50
100/100 $60
250/250 $80
500/500 $100

I'm on a grandfathered 150/150 for $50. I really don't want to increase my bill, but that sure is tempting.

General Discussion / 2.4 - Getting there!
« on: January 04, 2017, 10:54:15 am »

64% 248 issues   (124 closed 124 open)

Somewhere between 50% and 64% done!

General Discussion / Netflix 100Gb/s 45% CPU single socket E5

P.S 45% of E5-2697 v4 which is an 18core 2.4ghz.

General Discussion / PFSense needs a rebase
« on: October 09, 2016, 08:48:00 am »
386BSD 2.0 is finally made public on github. Make sure FreeBSD 11 is rebased against it before 2.4 is released

General Questions / Typical performance for mid-range desktop grade
« on: September 21, 2016, 06:33:34 pm »
i5-3.2ghz Haswell, Intel i320-T2
Finally got iperf3 to work setting the packet size. Decided to test against public iperf servers to see how my system handled it. While my desktop was CPU bound, PFSense seemed to be idle

1 iperf was capable of about 240kpps of 64byte UDP packets per core, four cores.

~240kpps 6% cpu load
~480kPPS 6.5% cpu load
~960kpps 7% cpu load

This was from LAN to public internet with traffic shaping. I also noticed when playing around with different bandwidths, it quickly approached 6% load, then as you see it plateaus.

What is a typical PPS for a medium end system?

P.S. Of course my uplink could not handle these bandwidths, lots of packetloss.

General Discussion / New TCP congestion algorithm - BBR
« on: September 16, 2016, 09:14:02 pm »

Google has been using it, lowers latency, increases throughput, works with modern AQMs, does not get starved by other algorithms in use. What's not to like? Best yet, does not require the receiver to interact in anyway special to get full benefit. Just upgrade your servers and watch the Internet be a nicer place for all.

General Discussion / Upcoming versions
« on: September 08, 2016, 09:43:03 am »
I keep seeing constant activity on redmine, 2.3.2_p2 isn't moving very quickly according to the graph, I see a 2.3.3 forum but nothing in redmine, 2.4's graph seems to be moving in the light green color, and FreeBSD 11 is nearly released. Seems like lots of stuff going on behind the scenes.
