Slow loading of static files hosted on GAE

My site (www.nykidplaces.com) is hosted on Google App Engine.

Loading the home page is sometimes very slow, 10 seconds or more. After some profiling, I noticed that the problem is usually caused by loading a static file (css, javascript or images). Most static files load quickly, but sometimes a single random static file will load very slowly.

For example, this 4Kb file usually takes <200ms to load, but sometimes takes much longer:

while true; do time wget http://www.nykidplaces.com/styles/toastr.css --quiet; done

real 0m0.163s

real 0m0.154s

real 0m3.335s slow

Any ideas on what might be causing this?

My .yaml file:

version: 1
runtime: python27
api_version: 1
threadsafe: true

handlers:
- url: / images
  static_dir: images
- url: / styles
  static_dir: styles
- url: / javascript
  static_dir: javascript
- url: /.*
  script: daycares.application

libraries:
- name: webapp2
  version: latest
- name: MySQLdb
  version: "latest"
- name: jinja2
  version: latest

It shouldn't be that slow, but I noticed that your static file is using the default expiration time of 10 minutes. You can tune it to a higher level 1 day to use a very fast cache cache for static files (if they don't need to be updated frequently)
