Selenium Node, slow hub register.

Selenium needs more entropy

I was trying to setup Selenium on a Digital Ocean Droplet and could not get Selenium nodes to register with my Selenium Hub. If it did eventually register, it took 30 plus minutes!

Very slow node startup. Why?

By chance, I found a comment on an unrelated Stackoverflow Selenium question. It mentioned entropy in regards to Selenium starting up so slowly.

After some searching, I found that entropy can be problematic on VPS hosting solutions like Digitalocean's droplets. Read their article for more information.

Haveged to the rescue

Installing Haveged fixed slow Selenium Node startups and hub registering.

apt-get install haveged

You may want to verify that it is running after the install completes.

sudo service haveged status
