What will happen if i will install ESM on the same server where my Gateway has been installed. I think there is performance issue, but can someone tell me what are the scenarios where i will face performance issue.
Or there will be no effect.
As Stephen mentioned in this discussion, that ESM is not recommended to be on the same machine as gateway
ESM implementation in Gateway
There can be an overhead in message processing. If there are performance problems and a support case is raised, support may ask you to uninstall it.
