FreeBSD / pfSense slow network with Hyper-V
For some reason, it took me way too long to find information about this issue – so I’m writing another article that will hopefully help some people.
IT Ticket # 1337
Problem Description: Network performance through pfSense is extremely slow with Hyper-V
Software Versions: pfSense 2.6.0 and Windows Server 2022 (August 2022 patches)
Steps Taken Already: Confirmed hardware TCP offload is disabled; confirmed hardware checksum disabled; confirmed MTUs were correct.
Solution: Read on for the solution (hint: it’s a known driver bug, and for now only a workaround exists)

Being a very technology-inclined person, electricity has an important role in much of my daily life. Many of my tools require it (I include computers in this category) and, when the power goes out, it is the absence of server noise that alerts me, not that of light. The best way to keep these devices running is with a UPS (see previous post on the subject).
Network
Above is the “defender of the Internet” – this UPS keeps the modem, router, gigabit switch (and in passing, my amplifier) powered in the event of a power outage.
This UPS was $15 at a thrift store, is rated for 350VA (so… 275W?), and originally came with a 7Ah battery. Naturally, the battery was toast. I instead ran some wire from the terminals to a 12Ah battery from a broken car booster pack. Yes, I simply wrapped the wire around the terminal.
I haven’t tested the life span, however I once left it unplugged, with my amplifier playing music, for 30 minutes without failure. Boredom led me to plug it back in. I expect it should last several hours powering only the network.
Server
The server has 8 hard drives, and consumes a fair amount of electricity (more than the small UPS can provide). Because of this, a much larger UPS is needed. While browsing Kijiji one day, it occurred to me that I’ve never checked there for a UPS before. It was a good thing I did this time:
Photo Blog – Serious Server Setup
The next many pictures will go through transferring good old BIGBLUE to a new 4U Rosewill RSV-R4000 case, and the installation of two new Western Digital Caviar Blue 1TB Drives!
From start to finish:
Upgrades to BIGBLUE (server)
Sorry to anyone who’s been trying to access the server the last 24 hours, I’ve had to take it down a couple times. I’ve just installed two new 1TB hard drives (RAID 1), and split the previous 750GB RAID 1 into two separate drives, giving me a total usable capacity of… 2.5TB! Seems like lots of storage now… but in a year I am quite certain it will be almost full, yet again.
I ordered the 750GB (x2) drives last November, and in a year I managed to almost fill them.
Of course, here is a lovely photo of the server, filled to the brim with hard drives! Beautiful, and awful at the same time.
6 drives, and not enough plastic rails to slide them securely in place (the bottom drive is just sitting there upside down). I’m out of SATA ports, but there’s still connections for IDE RAID!
Moved, new song!!!
The move is now complete. The server is back up and running, and hopefully there won’t be any issues for the next long while, thought if I move the server around in the room it may go down for a couple minutes. Good news: the internet here is faster than the last neighbourhood! Upload is around 540kbps, vs. the 280kbps I got at the last place. Upload is now 4.5mbps, vs. 1.8mbps. Nice!
I recently began a new song, and it has evolved into something of intricate instrumental interaction that is enjoyable to listen to. It is long, however I have always been a fan of long songs with many faces. My music, being instrumental, does not follow a pattern such as radio-bound music. A pattern of intro/verse/chorus/verse/chorus/bridge/chorus simply becomes too boring in an instrumental. Therefore, the music I write often does not have such defined sections, and instead takes advantage of multiple alterations of notes and instruments in order to keep it interesting and enjoyable.
Head on down to the music section to hear the new song!
Note: Server Downtime
Just a note: the server will be down, likely beginning sometime Saturday afternoon, though possibly either sooner, or later, than that. Once down, it will not be back until AT LEAST Tuesday, Feb 22. Reason: I’m moving, and as such, so is the server. The Internet connection will need to be transferred to the new house, and though we’ve notified them already in advance, well, I will never be one to vouch for quick response time from any of the involved companies…
Thanks in advanced for the patience, and hopefully the connection will be faster at the new place!
Update: it is.
Server upgrades, exams
Hello all! This evening I upgraded the server a little bit. Last Saturday I ordered two 750GB drives, on sale for $69.97 at TigerDirect.ca, and tonight I set them up in mirrored RAID. Now there are five hard drives in the server: amazing. (By the way, for those who don’t know why the hell I’d do this, the server is my back up device, so I can access my files from anywhere, and in case drive failure occurs on my already RAIDed desktop. As well, I store all my media on the server to share within the whole house.)
I’m only waiting for the power supply to die, but Thermaltake power supplies are incredible: they don’t die. This one is rated for 420 watts, and the one in my desktop is rated for 430 watts, and for my desktop, I’ve got three hard drives, two optical drives, and a 9800GT graphics card. Anyway, enough product placement, here are the innards of the server:
Awesome. So now there are: two 750GBs, a 200GB, a 320GB, and finally, a 20GB Quantum Fireball, which has Windows installed on it, along with all software. Amazing. This drive has got to be about 9 or 10 years old, but I don’t see it dying any time soon, and its running 24/7. They don’t make ’em like they used to. Here is a last beauty shot:
Now, as for exams. They begin for me next week, on Thursday. Wednesday is a day off, a “study day”. My last exam is December 17th, after which I get exactly a month off, from the 18th of December to the 18th of January. 🙂
In terms of class projects, I have only had one since the last posts: the AM/FM radio. I’ve finished mine, and I plan on providing a detailed overview of it quite soon. I should cover the phone as well. Perhaps over the break I shall! Here again is a shot of the radio. Expect an update soon!
