High CPU usage and low speed on win 8.1 1gbps network
6 replies, posted
Hello,
I've got a realtek nic on a MSI 890gxm-g65 and a PPPoE internet connection that connects on 1gbps and the ISP marketed speed is of 500mbps.
Does anyone have know why I get a maximum download speed of 499mbps on Ubuntu 14.04 and 200-300 on Windows 8.1 from the same source?
I've got the latest drivers (even tried 4-5 older versions) and updates. Also on Windows CPU 0 core (it's a FX-8350) spikes to 100% when the download speed reaches ~300mbps.
Are the Windows drivers so poorly optimized?
Thanks.
Long story short Windows can be a bag of shit a lot of the time. It can only be the drivers if it's faster on Linux
It could also be malicious software using a percentage of your network speed for a bot net or something.
You could try "Refreshing" your Windows installation, or running some anti-virus stuff like [url=https://www.malwarebytes.org/]Malwarebytes.[/url]
The PC is clean now and I've also tested the speed when windows was freshly installed in November last year.
Besides the drivers being shit, I'm out of ideas.
I'm going to go with Windows 8.1 drivers are terrible. I've seen thread after thread for months about Windows 8.1 driver problems.
But you also have the issue that a Realtek NIC isn't actually a NIC, it's a PHYceiver with a cheap ASIC with a bunch of registers. All of the data transfers are done in software on the host CPU, which slows things down, especially if the driver is shit.
Realtek NIC isn't actually a NIC pretty much goes out the window since on the latest Ubuntu it works just fine (499 out of 500 mbits seems legit).
A few days ago they released another driver that does not fix my issue. I've sent them an email but I doubt they'll respond or fix it (or even read it).

Because better drivers.
Linux isn't burdened with the bureaucracy of Microsoft driver signing and the anal idiotic requirements of Windows drivers.
