[CentOS] Slow to reboot

I have CentOS 7.2 installed and when I issue a reboot
I get a message about "A stop job is running" and its my process I start
with
a service file.

My service file just runs a script.
Type=forking
ExecStart=/path/to/myscript

What do I add so the reboot process goes faster  ?

My process does not need to stop anything before allowing the reboot.
No databases are open or anything...

Thanks,

Jerry
