Yes you can. We are using fixed size containers in the management segment as we are not using dynamic memory allocation during runtime. There is a default configuration which fits more to larger systems. Besides the memory pool configuration you can change these compile time constants. Check here what you can change via CMake switch. Especially the constants for publishers and subscribers are currently relevant

The maximum power you have if you directly check the constants in posh_types. But the ones available as CMake switch should be the most interesting ones

@Indra5196, did it work out? I would close this issue if you think the questions are answered
