Slowness to show ES when leaving a game

[nj180grados]

Hello people, I have noticed a very noticeable slowness of at least 10 seconds when I left a game to go to Emulation Station.
This happens to me very recently, I have put romsets and several systems to my retropie.
I have updated all the cores
I tried to disable runcommand
I have updated ES
I have reviewed the ES options
I have reviewed Memory Split
I have overclocked the RPI

I have tried all these options but I can not solve the problem. There is a very noticeable slowness when leaving the game until it shows emulation station.

Can anybody help me? This problem is very uncomfortable and before I did not happen I do not understand what happened.

Excuse my English.

I await your answers, thanks!

@nj180grados your romset are on sdcard or USB hdd?

Did you notice if you turned force_turbo off?
I think you would have stated if you were using a usb.
I haven't used romsets, I don't know how everything handles a huge job, but you say it was rather suddenly that you noticed and not after you add roms.

If you use ssh, you could login and type htop to display the processes to see if there is something slowing down.
