1. 之前用 ckeditor ，使用capistrano 3部署到远程服务器的时候每次都卡在rake assets:precompile，不知道有什么解决办法没有？
2. 我到 ssh 到远程服务器后执行RAILS_ENV=production rake db:seed, 也会话费很长很长的时间，通常也是直接卡顿。 下面我在本地进行rake db:seed的时间和远程的时间，有什么解决办法吗？

# local
$ rake db:seed

start seeds

end seeds
========================================

========================================
# ssh to server
start seeds
378.131025
end seeds
========================================
