I observe windows builds to time out while restoring the cache, for example here. The cache is a bit less than 500MB.
At the same time, I see caching working fine within about 30s with much larger caches here on linux machines…
Is this a general problem with IO on windows? (I had the impression that they are somewhat slower in general)
Reading through several other topics, it seems that poor performance seems to be a general problem with the Windows VMs.
Is there any hope that this will improve? Or should be try to workaround this in some way?
I checked this again and apparently the situation has not changed a lot. Not it even fails while packing the cache…
Is there anything I can do about that? Are there any activities to improve IO performance?
This PR should improve performance.
This is likely due to Windows Defender. This post shows how to disable it before cache download begins.
