Steam patching became extremely slow since the 150MB patch / high Content.gppk HDD reading

Before the patch for descent champions mentioned in the topic, patching via steam would be like any other steam download.
Max downloadspeed of my connection and directly startable after finishing the dl.

Since the 150 MB patch, it will always load seemingly single files at once, no streaming of all data, and constantly have extremely high HDD activity reading the Content.gppk file.
Patching the 5.2 MB patch right now takes about 10 minutes, of which 9 minutes were after finishing the download with 100% HDD activity reading Content.gppk all the time.

I have this same problem.

I have this problem too, but in addition since my disk space is so cramped it tells me I don't have enough disk space (which I clearly do, since I have around 4 GB open and it's a 5 MB patch...) so I have to go and find something to delete just to download a 5 MB patch in 20 minutes time

Still happening for the small patches like today.

The big 1.0.2 patch worked properly, however.

I'm still experiencing this as well. I have been experiencing these 10+ minute patches since the first Steam patch.
