Git installation maybe interfering with plink & gitlab

[c33s]

maybe this issue can be closed, i still wanted to open it to keep it as reference.

summary

i never had problems with git, putty and plink but after upgrading from git 2.14.1 to git 2.19.0 my remote commands (i tried pull and push) took ages (~30sec for a pull of a not modified repo).

my tests resulted in:

• detailed tests: https://gitlab.com/gitlab-com/support-forum/issues/3975
• problem started after upgrading git 2.14.1 to git 2.19.0
• only having the problem pull/push to gitlab.com
• no problem pull/push to github.com
• also had the problem while only calling plink -v -T git@gitlab.com
• friend of mine could reproduce the problem (no problem with plink before installing git, slow connection after installing it, deinstalling and reinstalling solved his problem. he was not able to reproduce the problem again)
• the issue on gitlab has 2 upvotes, so it looks like i am not alone
• workaround was to tunnel the connection over a linux server
• currently it works again, cannot relate a specific action to it

• [x ] I was not able to find an open or closed issue matching what I'm seeing
• maybe Very slow clone using plink #1538 is related

• Any other interesting things about your environment that might be related
  to the issue you're seeing?

• cannot use ssh-agent (connection timeout). i assume because of my firewall

• no problems with git before updating to git-2.19.0. i assume i had 2.1.14.1before (because its still in my download folder)

Details

• Which terminal/shell are you running Git from? e.g Bash/CMD/PowerShell/other
  cmder, bash & cmd (tried all three)

• What commands did you run to trigger this issue? If you can provide a
  Minimal, Complete, and Verifiable example
  this will help us understand the issue.

git clone git@gitlab.com:c33s/git_speed_test.git
cd git_speed_test
git pull

plink -v -T git@gitlab.com

• What did you expect to occur after running these commands?

fast response

• What actually happened instead?

very slow executing (28sec) even if the repo is small and no changes to pull. having GIT_TRACE=1 set i could narrow it to the execution of plink
