Bug

What is the current behavior?

Yarn takes more time on adding a single package.

If the current behavior is a bug, please provide the steps to reproduce.

https://github.com/bboysathish/react-boilerplate/tree/react-redux-router-hot-css

This repo uses yarn, try installing a single package and it takes 886.92s. (This is completely more compared to npm)

What is the expected behavior?

It should be fast and should not take this much time for every package addition.

Please mention your node.js, yarn and operating system version.

Node.js - 6.9.4
Yarn.js - 0.18.1
OS - Windows 10 - 32 Bit
RAM - 4GB

Dupe #990

[sathishsoundharajan]

@torifat May I know the solution ???? If windows is not supported we should add a note / banner saying Windows is not supported due to Antivirus and optimization problems.

[torifat]

Goto https://yarnpkg.com/en/docs/install#windows-tab then scroll down to read the Notice section.

@torifat I see #990 is closed. But still the issue exists.

[sathishsoundharajan]

@torifat i have excluded the node.exe and Yarn Cache folder from the Windows Defender scanning, i don't have any other anti-virus running now.

Still it takes 544s.
i think there is no definitive solution for this problem.
Can you please reopen this issue, so that people facing same issue like me can post their thoughts ?

For you reference you have already closed one another issue today (#2460).

[torifat]

Ok, I will test it in my Windows 10 setup.

[sathishsoundharajan]

Thanks @torifat

i have provided the sample repo above.

Steps would be

1. Yarn install
2. After installation happened, then try to install one another module to package E.g try yarn add [email protected],1 -D -E
