12.3.0 that was.

So it's chef-client filling it's cache rather than the in-memory chef-zero?

I don't use Vagrant, but I have noticed that "synchronizing cookbooks" takes a while lately..

What version of chef-client did "synchronizing cookbooks" start taking forever?

Ooops I was wrong: it was vagrant-cachier which made the situation actually a bit better. With cachier disabled it happens now every run, not only the first one.

Thought that these messages came from cachier, but it was chef-zero indeed?

With all the dependent cookbooks the "Synchronizing cookbooks" takes quite an amount of extra time (~4 minutes for apt, apache2, iptables, logrotate)

Would be great if there were a way to disable "Synchronizing cookbooks" for the vagrant case, because the cookbooks are mounted via synced_folder anyway, so there is no need for caching it internally

Any ideas?

Cheers, Torben

I was experiencing extremely slow chef runs as well with vagrant 1.7.4 and the chef_zero provisioner.

It turned out to be vagrant-cachier in my case, which caches "/var/chef/cache" [0] where chef_zero also stores it's cookbooks internally. Having vagrant-cachier caching these file by file was super slow, even with only a minimum set of cookbooks...

Actually I find it quite useful to cache "/var/chef/cache". 

Is there an option in chef_zero config to store the cookbooks anywhere outside the file_cache_path?

Cheers, Torben

I've been experiencing a similar problem on one of my machines (Windows 8.1) in a slightly different setup - using chef-zero standalone to bootstrap VMs that I've created using vagrant.

If I run chef-zero on either a host private network (e.g. using -H10.0.1.1) or on localhost (default), berkps upload perhaps loads a cookbook every 10-20 seconds. If I instead use the public IP of the host, it takes 1 sec or less per cookbook. 

I'm pretty sure this is a problem with my network setup (e.g. routing internal traffic wrong), just haven't had the motivation/ergs to figure out what, given I have the workaround of using my public IP address. I only mention this in case it helps suggest what might be going wrong for Greg's  case. Of course, I wouldn't be sad if it helped me figure out my issue too!

One thing I've found, for both Vagrant and any kitchen driver, is making sure my chefignore excludes the .kitchen directory.  When Berkshelf scans the cookbook directory, it likes to scan everything, and depending on how much is in your .kitchen folder, that could take a bit.  Plus, some drivers have open handles to files (especially on Windows) which can lead to errors.

Are you using chef_zero or chef_solo as your kitchen provisioner?

I'm seeing the opposite.  Same machine, same run_list.  "vagrant up" takes about 80 minutes, "kitchen converge" takes 7-8 minutes.

Sorry, I mean is it significantly slower to run vagrant up vs kitchen converge for the same developer on the same machine running the same logic path. I.e if you make a .kitchen.yml in the same directory as your Vagrantfile and configure kitchen to create an instance in exactly the same manner are the times similar or is vagrant slower? In the effort to isolate the problem, being file transfer, Vagrant or chef-zero. For me Vagrant is actually faster...

There's a couple of interesting things happening in the pipeline to speed up test kitchen runs using chef-zero, maybe similar could help you out if you're willing to sit out another monkeypatch into merge situation:

https://github.com/test-kitchen/test-kitchen/pull/466
https://github.com/test-kitchen/test-kitchen/pull/620

If you're using AWS for spooling instances I also found moving to t2.small from t2.micro to be a speed step up.

Yep, test kitchen / kitchen-vagrant converge times haven't changed much (or at all) with Vagrant 1.7.3 installed.

Out of interest do you get similar times if you spool up a local chef-zero instance and knife upload and/or spool up an instance using the chef_zero provider, just to make sure it's not Vagrant doing something strange?

That seems like a long, long time for spooling to me. I used kitchen-ec2 to spool instances on AWS and, granted my cookbook stack is probably smaller than yours, it takes maybe 15-20 minutes to spool an instance (so transferring over the internet).

Previous versions of Vagrant (1.7.2 and prior) used a fudged Chef Zero provisioner that was actually Chef Solo under the covers:  https://github.com/mitchellh/vagrant/issues/5072

This meant that all your data bags and the code that depended on them had to be fooled, stubbed, or coerced if you wanted to test it in Vagrant.  This was generally seen as a bummer and widely regarded as a time sink that produced little business value.  "That's what you get for using open source tools, Greg." 

We'd been waiting for Vagrant 1.7.3 over here for some time because it promised real Chef Zero support:  This should have made our hacks and dumb shell scripts obsolete, allowing me to give my dev's a Chef role and nothing else for configuring their development VMs  https://github.com/mitchellh/vagrant/pull/5339

And so it was like a child starting its first day of school and immediately after dreaming of christmas morning that we watched the above PR get merged and thought to ourselves "probably won't be more than 5 or 6 months before that gets bundled into an official release."

Today I can say that this does not fit in our workflow.  The Chef Zero provisioner is taking anywhere from 20 to 40 minutes on different laptops just to load our cookbooks into memory from local disk.  Then there's the speed at which it seems to be configuring the resources in a run list.  I don't have any real figures to refer to, just anecdotal evidence, so I'll resort to hyperbole.  Vagrant 1.7.2 and Chef Solo seemed zippy enough.  I could spin up a development vagrant machine in about 5-10 minutes depending on role and network.  1.7.3 and Chef Zero are reminiscent of a snail race through knee-deep peanut butter.

Sometimes we use Vagrant to test Chef changes locally before uploading to a CI server that will build a branch of chef code on EC2 and run some tests before we mark it as merge-able.  I'm telling Chef dev's in this organization that Vagrant is supposed to save them time, that local development is a convenience... and now this.  I literally can't even.  

Who's got a workaround for all these network round trips and molasses uploads?  Do I need more ergs?  Should I just rub some Docker on it?  Aside from declaring 'no joy' and rolling back to Vagrant 1.7.2 what are my options here?  We've tried different folder syncing methods (nfs, rsync) and found them all wanting.  I'm afraid this is a feature, not a bug:
