Why does a deployed Meteor site take so long to load?

For a very simple application, my Meteor site is taking 4.1s to start downloading the first byte of data. This is with a very basic setup. The relevant times etc (taken from http://www.webpagetest.org) are:

IP: 107.22.210.133
Location: Ashburn, VA
Error/Status Code: 200
Start Offset: 0.121 s
DNS Lookup: 64 ms
Initial Connection: 56 ms
Time to First Byte: 4164 ms
Content Download: 247 ms
Bytes In (downloaded): 0.9 KB
Bytes Out (uploaded): 0.4 KB

Is this due to Meteor being slow, or is there likely to be a bottleneck in my code? Is there a way to determine this?

Thanks.

According to webpagetest, that's:

the time needed for the DNS, socket and SSL negotiations + 100ms.

I loved the @ram1's answer, but I would like to add that it's also due to your server performance. That amount of time is common in shared hostings. There are two workarounds there: change your hosting or add a CDN service.

Also, it will help if you have less redirections.

You should make a better use of cache and, for Chrome users, you can apply the pre- party features.

That delay is a function of the time it takes your subscriptions to get data from the server. If any of the document data the client needs on page load is static, store it in unmanaged (unsynchronized) local collections so it is available immediately on initial page load. See collections.meteor.com for a load time comparison of data stored in an unmanaged versus a managed collection.
