I am working on wordpress website designing. I have a laptop DELL 5300 with 8gh of RAM and 512gb of SSD with i5 8th gen processor. Still it was so laggy while i was editing my website pages. I spent hours to fix this issues but still no fix at all.
i cleaned transients in wordpress settings, also deleted post revisions may be it work. But still no result at all. Then i found a post about this on the internet, someone suggesting Brave browser . i moved to brave, now i have updated all my content of my website. And its working smoothly.
