Hello, I noticed slow boot time on my system. I have SSD Plextor 128 GB M.2 2280 SATA III (PX-128S3G) and find it very slow comparing to old SSD 2,5’’ I have on another laptop. My main laptop is Dell Inspiron 7577, 16 GB RAM. I use Ubuntu and Elementary OS before and system boot was even slower. I don’t now is that SSD is so slow or the reason is I have also second disc HDD for /home?
I want to speed up my boot time and remove some unnecessary services. Can somebody tell me what services I can disable?
