I wanted to simulate 1147 gNBs and aprox 7000 users using 5g Lena but the problem is that I am running out of memory and the simulation is taking to long. Can you help me regarding this.

(1147+7000)^2 = 66 million channel realizations. It will take an awful long time. Regardless of any other setting.

You either use simpler channel models, which will be supported in upcoming NR 4.0.

Or use 3GPP channel model with clipping to discard signals at a given range.
Search for DistanceBasedThreeGppSpectrumPropagationLossModel.
It is currently set to a 1km range.

I also wanted to check — what's the maximum number of gNBs and UEs you've been able to stress test? And how much time should we anticipate the process taking?
