Google chrome slows little bit

Hi everyone,
I use Google chrome from long time. But now it slows.
When I check task manager and i saw 4-5 processes running.
It slows my computer also.
When I start it i had to wait 30 seconds before working with it.
Untill 40 seconds it stuck.
It became a headache for me.
Please give me solution.
Thank you!
