Hello @howdev, the usage you've described is within expectations for SteamPipe.

howdev commented 4 years ago

If that is the case, does that mean SteamPipe uses more CPU than other applications that download?

If SteamPipe uses this much CPU when downloading, then is not suitable to play a game and download at the same time, since it will reduce the performance of the game

howdev commented 4 years ago

What does SteamPipe actually do that use this much CPU?

Plagman commented 4 years ago

It does a lot of decryption, decompression, and delta-patching work. You're right that in some situations, it's not suitable to play a game and download at the same time; for this reason, I believe downloading games while playing is off by default and has to be explicitly enabled by the user.

@kisak-valve what is within expectations for download CPU consumption? I've recently noticed my client get up to ~100% cpu during downloads. I'm pretty sure this only started in the past month or two.

Experiencing the same.

Same issue, system was almost unuseable while Steam was downloading a new proton prefix. This is unacceptable.

I just started downloading Phoenix Point, and steam consumed over 300% CPU on an AMD 5600X pretty much the whole download.

 PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND

I see this is marked as "Not a bug" -- is that accurate?

I'm on Linux 5.14.8-arch1-1, with the Sept. 17th steam build.

I have an AMD Ryzen 5 2600, but my cpu usage in top -i and htop seems really high as well and I'm just updating my games. g5k2a

Because of this, my cpu is running at 75 - 80 C instead of 50-60, and it also means I need to keep everything else closed if it is downloading...

I'm using a more recent version of Arch Linux than rcorre is: 5.14.14-arch1-1

I'm using Steam downloads for cooking bacon (vegan bacon).

Do you like crossfit? Btw I use arch while my laptop cocks my vegan bacon.

es20490446e commented 2 years ago

They banned me in Arch, and I have never looked back.

Now I have my own packaging system, with over 50 packages.

Tell the Arch guys that they can suck my brail.

MartinX3 commented 2 years ago

I don't know how to achieve that, but I also have a list of people who can suck my toilet seat, especially in the IT.

es20490446e commented 2 years ago

Their lost 😛

MartinX3 commented 2 years ago

Maybe they should accelerate themselves on the GPU 🧐

+1 also using a ryzen 5 2600

limiting it to 500mbps instead of allowing it to reach about 800mbps (I have gigabit internet) reduces the CPU usage drastically and no longer causes my system to stutter
