Tool to optimize SIS global/domain publishers

Hi,

I would like to know is there a tool available that can help in optimization of global/domain publishers.

We have project where we are at a limit of 16 System Global Publishers used.  This system has several domains over 250 logic solvers in total.

Many optimizaions were already done and we are using doman publishing wherever possible, and we transfer the needed global publishers through a specific logic solvers in the domain that were promoted to system publishers.  However, for further optimizaion a good tool would help.

Any ideas?

Regards,

Marko
