gitlab slow when running on nginx subdomain

Question

I'm trying to run gitlab on a subdomain. I installed the latest gitlab version using the omnibus installer on my vserver (running Ubuntu 14.04.1) and disabled the bundled nginx and configured the unbundled nginx with the configuration posted here How to setup a subdomain on nginx?

/etc/nginx/sites-availible/gitlab

upstream gitlab {
    server unix:/home/git/gitlab/tmp/sockets/gitlab.socket;
}

server {
listen 80 default_server;         # e.g., listen 192.168.1.1:80; In most cases *:80 is a good idea
server_name git.domain.com;     # e.g., server_name source.example.com;
server_tokens off;     # don't show the version number, a security best practice
root /home/git/gitlab/public;
client_max_body_size 500m;

# individual nginx logs for this gitlab vhost
access_log  /var/log/nginx/gitlab_access.log;
error_log   /var/log/nginx/gitlab_error.log;

location / {
  # serve static files from defined root folder;.
  # @gitlab is a named location for the upstream fallback, see below
  try_files $uri $uri/index.html $uri.html @gitlab;
}

# if a file, which is not found in the root folder is requested,
# then the proxy pass the request to the upsteam (gitlab unicorn)
location @gitlab {
  proxy_read_timeout 300; # https://github.com/gitlabhq/gitlabhq/issues/694
  proxy_connect_timeout 300; # https://github.com/gitlabhq/gitlabhq/issues/694
  proxy_redirect     off;

  proxy_set_header   X-Forwarded-Proto $scheme;
  proxy_set_header   Host              $http_host;
  proxy_set_header   X-Real-IP         $remote_addr;

  proxy_pass http://gitlab;
}

I'm able to visit the page, but it needs 30s and more to load the page. It is not taking so long when I'm using the bundled nginx server so I don't think it is a memory issue (and free is telling me that theres 1,4GB availible)

The error log tells me something like this:

/var/log/nginx/gitlab_error.log

server: git.mydomain.de, request: "GET /assets/application-c4186ca579dd09b3e48eaf1b5a3e4434.js HTTP/1.1", upstream: "http://unix:/var/opt/gitlab/gitlab-rails/sockets/gitlab.socket:/assets/application-c4186ca579dd09b3e48eaf1b5a3e4434.js"

Thanks a lot for helping!

Update: Upgrading to Gitlab 8.x fixed this issue for me

Original Answer:

I had this same issue and resolved it by directly copying the generated nginx config from the gitlab install to my nginx config directory.

I found my gitlab nginx config at: /var/opt/gitlab/nginx/conf/gitlab-http.conf

Pasting it here for posterity:

##        CHUNKED TRANSFER      ##
##################################
##
## It is a known issue that Git-over-HTTP requires chunked transfer encoding [0]
## which is not supported by Nginx < 1.3.9 [1]. As a result, pushing a large object
## with Git (i.e. a single large file) can lead to a 411 error. In theory you can get
## around this by tweaking this configuration file and either:
## - installing an old version of Nginx with the chunkin module [2] compiled in, or
## - using a newer version of Nginx.
##
## At the time of writing we do not know if either of these theoretical solutions works.
## As a workaround users can use Git over SSH to push large files.
