Very slow speed in upload

[mario rossi]

Hi, I recently updated to the latest version of Vagrant (1.8.1) and for some reasons it is now _very_ slow to upload files via http.

I use NFS and I can successfully copy huge files between shared mounts at a decent speed, but port 80 is really really slow.

I tried different uploaders, so it's not something with the code. do you have any idea of what it could be? 

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

  config.vm.hostname = "poorthing"

  config.vm.synced_folder ".", "/localhost", type:"nfs", :mount_options => ['nolock,vers=3,udp,noatime']

  config.vm.network "forwarded_port", guest: 80, host: 8080

  config.vm.network "forwarded_port", guest: 15672, host: 15672

  # Required for NFS to work, pick any local IP

  config.vm.network "private_network", type: "dhcp"

end

 thank you

Hello. if you are using the port 8080 that goes over the nat of virtualbox.

Try to use the ip set from private_network. ifconfig will show you the ip, and try with that ip as test.

If does better, you can put a fixed ip, and use that ip that will be directly from host to vm without nat.

You will be using a virtual nic on the guest, so you could test different virtual nics and see if that does any better.

Hello

Cool that worked for you.

My other suggestion was that you can test other virtual nics and see what goes faster.

Lots of things to test, example:

  config.vm.provider "virtualbox" do |vb|

    vb.customize ["modifyvm", :id, "--memory", "2048"]

    vb.customize ["modifyvm", :id, "--cpus", "2"]

    vb.customize ["modifyvm", :id, "--nictype2", "Am79C973"]

  end

2 is for the 2nd nic, the first one after the nat .. 

Types of nic:

                            [--nictype<1-N>Am79C970A|Am79C973|82540EM|82543GC|82545EM|virtio]

You can also test hw assisted virtualization:

                            [--paravirtprovider none|default|legacy|minimal|hyperv|kvm]

none is what is used today, but kvm should do the trick in new linux kernel

    vb.customize ["modifyvm", :id, "--paravirtprovider", "kvm"]

Alvaro.
