Slow startup of Selenium-Server-Standalone on OSX

Question

Selenium-server-standalone has a 5 seconds delay while starting. If I run selenium with debug option it shows that the delay is caused by New random session seed.

I start Selenium server with java -jar selenium-server-standalone-2.44.0.jar.

If I want to specify chromedriver then I write java -jar selenium-server-standalone-2.44.0.jar -Dwebdriver.chrome.driver=chromedriver_2.11

It happens with:

• OSX 10.9.5 and OSX 10.10
• Java 1.7.0_51 (update 67 and update 71)
• selenium-server-standalone 2.42.0, 2.43.1, 2.44.0
• with and without chromedriver (2.9, 2.10, 2.11)
• running as sudo and as non-priveleged user

From what I know on other machines with the same configuration there is no such delay.

It may seem that 5 seconds is nothing, but I have another issue that most probably is caused by the same problem. It gives me 1 minute of waiting instead of few seconds.

Here is the log
