general advice for development

Here are directories to exclude

• development project directories that contain .git repos or node_modules, etc
• docker image directories
• anything with thousdands of files

What services to configure exclusions on

• add directory to Windows Defender Exclusion list https://support.microsoft.com/en-us/help/4028485/windows-10-add-an-exclusion-to-windows-defender-antivirus
• add directory to Windows Indexing exclusion list-- Control Panel -> Indexing Options -> Add all of your development directories

Do this and you will notice Docker & WSL will be 100x faster

I am seeing exactly the same thing, I have done as suggested and excluded all the relevant directories from Windows Defender. Is there anything else I should be looking at?

@campbellm Next step would be to install procmon https://docs.microsoft.com/en-us/sysinternals/downloads/procmon . That gives detailed process activity listing all system calls and open files. That's how I found the above solutions. You may have another background process , or the exclusions above may not have been configured properly

I have the same issue here, I've added my development folders to the Windows Defender exclusion list without any performance improvement.
I've launched procmon and found a relevant event:

Is that a Docker network issue?

Try to disable windows defender at all, just for testing. You can use Windows Shutup 10 Tool to do this for sure.

I always disable my vaccine softwares when I run docker.
But it's extremely slow even there's no program running on my desktop.

I've assigned more CPU, RAM, SWAP spaces for moby linux, but it never gets better..

I guess it's not the problem of storage access. I think it's related to docker's virtual network accessing speed

Have been encountering this on a Windows 10 Enterprise (1709) laptop.

I strongly suspect that it's related to the use of VPN.

I'm using Citrix NetScalar Gateway. The performance of "docker ps" is abysmal when I'm connected, but fine when not.

I'm also encountering "No such container" error when trying to stop a container that is running (visible in ps), though whether that's directly related or not, I'm not sure; I don't know enough about the internals, but it all seems communication-related...

I tried to:

• Remove Docker
• Remove every remaining Docker configuration files
• Remove Hyper-V
• Remove all remaining network cards linked to Docker/Hyper-V
• Reinstall Hyper-V
• Reinstall Docker

without any improvement...

I ended by formatting and reinstalling Windows, everything runs smoothly now.

I disabled Windows defender and it help a lot. But the network between containers seems slow... any ideas?

I have also been experiencing abysmal performance and found that, at least in my case, it was related to pending updates. (I suspect Windows Defender)

I was working this morning and everything was fine. Came home this evening and everything sucked. (docker ps -a took around 4 minutes to respond) I tried everything: Restarting, shutdown and "cold boot", dns flush, nothing helped to improve the performance.

As a last resort decided to try checking updates. Three brand new updates were pending (Defender Antivirus Definitions, .NET Framework cumulative updates and Windows cumulative updates) so I installed them, rebooted and now everything seems to be back to normal.

It is definitely also worth noting that this only happened when connected via VPN. Without the VPN the docker ps -a command returned near instantly. The moment a VPN connection is established, that command stops responding and takes ages to return anything.

In my particular case, it would seem that VPN and Windows Updates are somehow connected, most likely due to the Defender updates.

For me, the problem disappears immediately when I just disconnect from my regular home WiFi.
I have tried everything with Windows Defender, but that has no effect on my machine.

I'm developing a PHP project on docker with image centos host apache 2. Process a page very slow.

After tried all your above suggestions and after I found when I turn on debug from VsCode. It run so fast fast. Surprised me!

1. Disable Antivius / Add process exclusive on window defender
2. Re install docker
3. Remove ipv6 of card network windows
4. Start container with disabled ipv6
5. Setting xdebug with remote host local
6. Turn on debug of VsCode

Thanks all Guys

Remove ipv6 of card network windows works for me.

I am working with docker on win-10. Until before a week was everything working perfectly. Since the last week docker is extremely slow. I tried a lot of things, like uninstall and install again, restart etc. Nothing worked.
Coincidentally I changed from WiFi to LAN connection and at this moment it works again perfectly. I don't have any idea why is this happening but maybe it helps somebody to understand more.

This is exactly because of [x] Send usage statistics. Uncheck this and run faster.

i can't get docker ps to respond on windows. It started when i ran docker-compose ps, and it didn't respond... I ran docker ps today before I fell asleep, 5 hours later, it is still stuck. very odd.

We have a project whose complete test suite takes an hour on a MacBook running docker. On a comparable Windows 10 box the unit tests by themselves take over 15 hours (the Behat tests can't run at all, without hacking the scripts so they won't time out):

If your issue is related to windows 10 and using a wifi adapter, try to disable all bridge protocols in the the advanced settings of your wifi adapter. Reference: https://superuser.com/a/540885
Afterwards "docker version" responds immediately.

I have this problem since last month, trying to disable ipv6 and netbios from all network, re-install docker, but no luck.

I end up using docker via WSL.

Weird thing is, I've installed docker for windows in 4 machines, but only one that has problem.

for me issue was when i have onedrive syncing at same folder stopping onedrive make it 100X faster
