Sorry maybe I wasn't clear, the results are the same on my PC workstation too, basically any Windows 10 PC.

Hi guys, A bit of an odd discovery here, hoping some networking wizards can figure this one out. I have a 500/100 fibre connection. When I run a speedtest (it's my ISP's own) on iOS or MacOS I consistently get around 500Mbps down and 100Mbps up. No issues here. The problem is on my PC workstation, whilst I do get around 500Mbps down, the upload appears to be capped at around 70Mbps. I can run the test 50 times over, day or night and it's are aways the same. At first I thought it might be the 10gig NIC in my PC, so I updated the firmware and drivers for this, no difference. I then tried my on board/mobo NIC, no difference. Now this is where it gets a little odd: On my MacBook Pro if I boot into MacOS and run the speediest in Chrome I get 500/100. If I then use bootcamp to boot into Windows 10, and run the same test (on the exact same hardware!) back down to 500/70. So from this I can only conclude that the issue is with Windows 10 itself, can anyone figure out why this would be the case? The screenshot attached shows the upload speed difference between Windows 10 and MacOS. In this instance I was testing Windows 10 on the same hardware via bootcamp but this capped upload appears to be an issue on any Windows 10 PC on my network too. Thanks in advance

Has anyone been able to source a Threadripper in the UK? I've been trying to get a couple of 3970X's for a few months now and every time an 'expected' date is reached it gets pushed back. For example Scan had them down for today, so I checked this morning and it jumped to March 2nd.

Hi Guys, Another update, just to confuse things EVEN FURTHER... I have just discovered that if I connect to our VPN via IKE v2 in OSX then there is absolutely no issue at all, my download hit almost 50MB/s immediately! Great! The only problem is.. I simply cannot connect this way in Win 10. I've tried via both the Windows VPN setup and also the Draytek Smart VPN Client, both methods appear to reach the server and ask for username/password, but as soon as I enter them they both produce these errors: IKE authentication credentials are unacceptable I'm using the exact same login details as I used in OSX, and that connects instantly! Any ideas? Thanks

Thanks guys, that explains a lot but also confuses things further from my tests this morning. I ran the following with no other traffic on our network: I setup a second Workstation at this location, same configuration as my primary Workstation. Workstation A: Connect to VPN SSL - Download file via File Explorer = 25MB/s Workstation B: Connect to VPN SSL (different account) - Download file via File Explorer = 25MB/s If I run these at the exact same time, I can see that the 25MB/s gets split between the two. Workstation A = 15MB/s Workstation B = 10MB/s To confuse things further, I removed Workstation B from my network and connected to a 4G network via my phones hotspot. I then connected to the VPN and started downloading the same file, this hits 5MB/s which is about right for my cellular connection. But.. Workstation A remained at 25MB/s whilst this process was happening simultaneously.. the second workstation had no impact on this apparant 25MB/s limit whilst it was also downloading.. Does this make any sense to you guys? In my head this suggests the the limit is based on location/IP as opposed to different VPN accounts. Thanks again

Thanks @jsf that's really interesting. I was kind of hoping this was the answer but this makes it even more of a head scratcher. The NAS I'm pulling the test file from is SMB2 (in the office I can move this file locally at about 112MB/s). Also, to confuse things even further, we do also have an older NAS which is SMB1. I enabled SMB1 support on my Win10 remote workstation and used this same test file to downloaded via the same method over the VPN. Based on your info I expected this to be even slower, but it actually downloads faster. Not massively, but definitely consistently faster. My results are as follows: NAS A (SMB2): Download via SSL VPN using File Explorer: 25MB/s NAS B (SMB1): Download via SSL VPN using File Explorer: 29MB/s It also looks like that 25-29MB/s limit gets shared into to two when I download from both NAS's simultaneously. If I download from one NAS via the VPN and also download a second file from it simultaneously but via the public ip (VPN bypassed) then my full bandwidth gets shared up. I've attached examples to hopefully better explain.. Thanks again

So after some further testing I have discovered the following: These are all whilst connected to our VPN via SSL protocol: Download via web gui via public IP (VPN bypassed) = 50MB/s Download via web gui via local IP = 41MB/s Download via File Explorer (Win 10) via local IP = 25MB/s I appreciate that there will be some overhead with the VPN, which is why I'm seeing 50 drop to 41, but does anyone know why this takes a massive hit when using File Explorer. As @Kilrah said this could be due to the packet type, but this seems lke a huge difference, or am I just expecting too much here and this is to be expected? Thanks in advance

Hi Kilrah, Thanks for the info, is this a common issue? Can you advise of a route to rectify this? We're using the Draytek Vigor 3910 firewall router which handles our VPN and DHCP. Draytek themselves insist there shouldnt be an issue, and switching VPN protocols shouldnt make any difference to our transfer speeds but clearly it does, and they didnt mention SMB packets at all.. Thanks

Hi guys, This one has our network installer, ISP and hardware manufacturer stumped so if any of you can figure this out.. heroes! At our office we have a 12-bay Synology NAS which is sat on our gigabit ethernet lan. We also have a Draytek 3910 firewall which handles our VPN and a 900 Mbps down / 500 Mbps up fibre internet connection. I have a large (20+GB) file on the NAS which I can move over the LAN to my PC Workstation at around 112MB/s. I now have my workstation at home, and I am connected to the office via VPN. My home internet connection is 420 / 50 (same ISP as the office). If I navigate to the web UI of the synology via our public IP I can grab this same 20GB file and it will download at around 50MB/s. No issues here. If I then connect to our VPN and navigate to the web UI of the synology via it's local IP I can grab this same 20GB file and pull it down at around 42.6MB/s. I guess this is still about right as there is a little overhead for the VPN. But our issue is this: When accessing the share using file explorer in Windows 10 (still via VPN and local IP) the transfer speed appears to max out at around 25MB/s. What's even more bizarre is if I change our VPN protocol from SSL to L2PT then this drops even further to around 10MB/s. But transferring the file via the web interface from the same local ip still hits 40+ MB/s. Does anyone have any idea what's going on here? I can provide further info if needed Thanks in advance!

Can anyone help?

Hi, I recently did a clean install of Windows and thought I would take the opportunity to update my BIOS. I'm running an Asus X299-E Gaming and I have an Intel 7940X which has a Corsair AIO. This machine was built for me and had a pretty stable 4.2GHz OC. Obviously I have now lost this OC since the BIOS update and to be perfectly honest, I have no idea what I'm doing in there (yes, I am kicking myself for not taking note of the configuration prior to update). Can anyone help me get this back to where it was? (I have no idea where to start). All I have done so far is enable XMP, the rest is a little over my head. I know the Turbo for this CPU is supposed to be around 4.3Ghz but since returning to stock I havent seen HWMonitor report higher than 4Ghz. I do a lot of all core CPU rendering and this now appears to max out at around 3.6GHz under all core load. Thanks in advance!

I finally fixed it! It turns out that if your hardware isn’t EXACTLY as it was when you made the disk image then the image won’t restore. I had since installed a 10gbe NIC, and discovered that as soon as I removed this and tried to restore the image again.. bingo!

What’s also interesting is if I look in the backup and restore settings in windows it doesn’t actually see the image. Even though I can see it’s there on the attached USB drive:

I don’t think it’s hardware, I’ve just managed to do a clean install of windows 10 in the hope that I could then restore from the image. Windows 10 all up and running fine, created a bootable USB restore to get into recovery environment, booted into that, went to image restore, it sees the image, click next, warns about formatting the disk, next.. and:

So I found a restore image I made when I first built this pc a couple of years ago. It’s on an external USB 3 drive. i plugged the drive in, booted to recovery via the window DVD, chose restore from image.. it found the image on the drive and stated the following: I clicked next to begin, the restore started, and then this: urgh! I tried first formatting the SSD via diskpart and also just creating one big partition and setting it as active. No joy. I also tried starting the windows install and allowing it to create the partitions, I then quit and ran the image restore again, same issue. Please help!
