==Warm up Varnish Script using Sitemap.xml==

I noticed after doing some random testing on my site that if I do a nightly warming of varnish, my site loads fast with varnish.

I have cache set for about one day, so nightly varnish warming has helped with site speeds.

Here is what I am currently doing:

===Create a URL list file===

1) Create a list of all urls on the site via the sitemap.xml file

curl --silent http://briansnelson.com/sitemap/sitemap-briansnelsoncom-wiki_-NS_0-0.xml | grep \<loc\> | sed 's/.*<loc>//' | sed 's|</loc>||' > ~/sitemaps/urllist-briansnelson.txt

Now that you have the list of urls on yoru site via the sitemap

===Seige your site using the list of urls===

Now this kills two objects with one stone

1) It gives a daily report of site performance ...yaaa
2) Warms the varnish cache

You can manually run siege to visually see the results

sudo siege -c100 -d5 -r1 -v -i -f ~/sitemaps/urllist-briansnelson.txt

===Setting up Siege to run Via a nightly cron===

Now lets set it up as a nightly cron

0 0 * * * /usr/bin/siege -c100 -d5 -r1 -v -i -f ~/sitemaps/urllist-briansnelson.txt

You can run this script as often as you like to keep your varnish cache warmed up, I run my nightly as I do not refreash my cache that often.
