Linux 6.8 Network Optimizations Can Boost TCP Performance For Many Concurrent Connections By ~40%
Now, gamers will want to play on Linux for the low latency on online games.
I'm not an expert, but I suppose as this patch is on the kernel and not on the game, this will still improve any connection your kernel needs to do, like sending telemetry of your anti-cheat engine and other apps that make TCP requests while you are playing online games.
Unfortunately, many games where people care about that lower latency tend to be competitive with some kind of anti-cheat that doesn’t mesh with Linux.
Somebody please temper my expectations because this seems like an absolute game changer.
You're not a cloud server that needs to run this many concurrent connections (probably)
Well I am, so that's exciting
No but my friend is cloud server with many concurrent connections and may want to hear the good news!
The test data on article is about server setup which is the right use case for this change.
Moreover the L3 cache on CPU is what makes significant difference, IMO.
If that is true, not sure how much improvement consumer-grade desktop will see, given that most consumer-grade CPU will not have that much L3 cache on chip.
This is the best summary I could come up with:
This effort has been around optimizing cacheline consumption and adding safeguards to ensure future changes don't regress.
In turn this optimizing of core networking structures is causing TCP performance with many concurrent connections to increase by as much as 40% or more!
This patch series attempts to reorganize the core networking stack variables to minimize cacheline consumption during the phase of data transfer.
Meanwhile new Ethernet driver hardware support in Linux 6.8 includes the Octeon CN10K devices, Broadcom 5760X P7, Qualcomm SM8550 SoC, and Texas Instrument DP83TG720S PHY.
NVIDIA Mellanox Ethernet data center switches can also now enjoy firmware updates without a reboot.
The full list of new networking patches for the Linux 6.8 kernel merge window can be found via today's pull request.

This proves once and for all that Linux is the superior platform!
when was the last time you heard any such news for PC or MAC?
when was the last time you heard any such news for PC
A few seconds ago, when I read that the new Linux kernel contains TCP related performance improvements!
This has to be some sort of Dunning-Kruger effect right here...
Dunning-Kruger
This is more a case of tongue-in-cheek
