How to improve speed performance

Hi,

I am using Sydney Free version and I like the design much but unfortunately, I realised that the site speed is slow and Google Console and site analyzer identifie several issues with this speed issue - https://gtmetrix.com/. Gtmetrix rated this site as E.

One is top page slider action and also some CSS settings and suggests to elimiate unused CSS.
I am new to WordPress so I am hesitate to change CSS settings by myself. Is there any way to speed up and improve site?

Thank you for your support.

However, I can only recmmend reading these instructions:

I hope that helps.
