What is it we're looking at here? The thumbnail is pretty small. Can you give more info, lighting setup etc?

Without knowing the scene, I bet it's missing a portal.

i was seeing this help page:
https://coronarenderer.freshdesk.com/support/solutions/articles/5000515603

Correct setup is: Rays/s: 6,195,195
whats Rays/s....? is it LSM or MSI...?

Rays/s is not a render setup option, it's render statistics. You can see it in virtual frame buffer when rendering is in progress or after it is stopped.

What I should have asked is, how have you lit your scene?

[Eddoron]

€5 on the portal or wrong lighting

Edit: @ iacdxb: please don't ask how many rays.

[iacdxb]

ahhhh... you asked light and replies render....! wow, last day was with full mess. But anyhow... fixed.

It was product stand all side open (I dont think need portal) full black (matt and glossy) and every shelf with inner light, in that I used light material which I think was causing noise... and somehow material was also a bit wrong in that....!

I hope its clear now... what your suggestion.

Get that €5 ready! ;)

Yep, I've looked at your file and have fixed it. The directionality of the light was set to bounce back on itself which I don't think is all that necessary in this case. Switching it to .5 (even) made for an acceptably denoised image.
