Impact when moving from 2048 to 4096 bit RSA keys

Hi, I am trying to determine the impact of moving from 2048 bit RSA keys to 4096 bit RSA keys for a clientside ssl profile and would like to get some details of the impact when doing so.   I read...

Hi,

 

Changing from 2048 to 4096 bit keys, would reduce number of supported TPS as you have noticed/got the information. However at the same time it would need more resources as well to cope up with 4096 bit keys. Hence it might depend that what hardware do you have where you would like to change the key.

 

I would suggest that involve account manager to get more concrete information on this.
