Very slow ssh copy (scp) during CI

Hi!
Final stage of my CD pipline is deploy to dev server. Now it is done by copying files over ssh. Overall size of files is approximately 45 Mb, ~ 2.8k files. When I copy thne from my computer (50Mbps internet connetction) it takes about 2 minutes to copy them all. But when they copied from gitlab.com runner it takes more than 1h and I get timeout error. Here is my .gitlab-ci.yml:

stages:
  - deploy

.deploy_template: &deploy_tpl
  stage: deploy
  allow_failure: false

.dev_deploy_template: &dev_deploy_tpl
  <<: *deploy_tpl
  variables:
    DEPLOY_HOST: myhost
    DEPLOY_USER: myuser
  before_script:
    - 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'
    - eval $(ssh-agent -s)
    - echo "$DEPLOY_PRIVATE_KEY" | tr -d '\r' | ssh-add - > /dev/null
    - mkdir -p ~/.ssh
    - chmod 700 ~/.ssh
    - ssh-keyscan $DEPLOY_HOST >> ~/.ssh/known_hosts
    - chmod 644 ~/.ssh/known_hosts
  only:
    - develop

api to dev:
  <<: *dev_deploy_tpl
  image: php:7.1
  environment: api dev
  cache:
    untracked: true
    paths:
      - api/vendor
      - ~/.composer
  script:
    - apt-get install -y pkg-config git unzip
    - pecl install mongodb
    - docker-php-ext-enable mongodb
    - php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
    - php composer-setup.php --install-dir=/usr/bin --filename=composer
    - rm -f ./composer-setup.php
    - chmod +x /usr/bin/composer
    - cd api/
    - composer install
    - ssh $DEPLOY_USER@$DEPLOY_HOST -C "mkdir /var/www/api/$CI_COMMIT_SHA"
    - scp -r -C ./* $DEPLOY_USER@$DEPLOY_HOST:/var/www/api/$CI_COMMIT_SHA
    - ssh $DEPLOY_USER@$DEPLOY_HOST -C "ln -s /var/www/shared/.env /var/www/api/$CI_COMMIT_SHA/.env"
    - ssh $DEPLOY_USER@$DEPLOY_HOST -C "ln -s /var/www/shared/runtime /var/www/api/$CI_COMMIT_SHA/runtime"
    - ssh $DEPLOY_USER@$DEPLOY_HOST -C "unlink /var/www/api/current && ln -s /var/www/api/$CI_COMMIT_SHA /var/www/api/current"
    - ssh $DEPLOY_USER@$DEPLOY_HOST -C "/var/www/api/current/vendor/bin/phinx migrate"

front to dev:
  <<: *dev_deploy_tpl
  image: node:10
  environment: front dev
  cache:
    untracked: true
    paths:
      - app/node_modules
      - ~/.node-gyp
      - ~/.npm
  script:
    - cd app/
    - npm install --no-audit
    - npm run build
    - ssh $DEPLOY_USER@$DEPLOY_HOST -C "mkdir /var/www/html/$CI_COMMIT_SHA"
    - scp -r -C ./* $DEPLOY_USER@$DEPLOY_HOST:/var/www/html/$CI_COMMIT_SHA
    - ssh $DEPLOY_USER@$DEPLOY_HOST -C "unlink /var/www/html/current && ln -s /var/www/html/$CI_COMMIT_SHA /var/www/html/current"

chat server to dev:
  <<: *dev_deploy_tpl
  image: node:10
  environment: chat dev
  cache:
    untracked: true
    paths:
      - chat-server/node_modules
      - ~/.node-gyp
      - ~/.npm
  script:
    - cd chat-server/
    - npm install --no-audit
    - ssh $DEPLOY_USER@$DEPLOY_HOST -C "rm -rf /opt/chat-server/*"
    - scp -r -C ./* $DEPLOY_USER@$DEPLOY_HOST:/opt/chat-server/
    - ssh $DEPLOY_USER@$DEPLOY_HOST -C "rm -f /opt/chat-server/server.json && ln -s /opt/shared/server.json /opt/chat-server/server.json 2>&1 > /dev/null"

I have a similar speed issue when pulling from the registry. I had hoped that gitlab’s migration to Google cloud last weekend would have helped, but no luck.
