Oh yeah steam is an entirely new ball game, there is hash checks and compression stuff going on.

Downloading on steam on gig1 is like I am running cinebench on the PC.

This seems to be the limiting factor on Steam Deck for me, it averages around 60MB/s but Fast.com can do 930Mbit and LibreSpeed from my NAS can hit 1.7Gbit over WiFi6.

Its curious Valve made a big deal about the newer WiFi chip on the OLED given in practice (I have both) I get identical performance due to the CPU limit.  But I guess WiFi 6 should perform better for most people who aren't sat on top of their AP, or have crosstalk issues.

I downloaded FF15 to a spare PC (not for this thread, but I took screenshots of the progress for the science).

Ironically thing ended up getting bottlenecked by sata SSD.

Some screenshots.

CPU for reference a 9900k.
MX500 SATA SSD.

That's interesting, you'd need 4Gbps to max out a straight write to a SATA SSD.

Yep, thats steam for you.

If you curious the game is final fantasy 15 which is a nearly 100 gig base install.

On a normal network transfer even a spindle can handle gigabit writes.

My guess would be sometimes those multiple small files will be downloaded compressed together, so will not suffer the constant stop/start issues but then a SATA SSD will get hit by its IOPS limit once its extracting those files.

Even on a top-end NVME drive I've found the patching system makes it often slower to do updates than to download the entire thing from scratch again.

People look at how fast SSDs are for sequential read/writes and completely format the random small read/write speeds.

More than likely the unzip of the packets was!

Yeah up until this point I think all my gig1 steam downloads have been straight to NVME, this one is SATA because I have the 9900k setup with spare parts, and I needed to add myself as a second player in the game. (due to the online community now being non existent).
