ESP - Improving performance of REST API XCF communication

[Jonas Dusil]

Dear ESP community,

We are pleased to announce the release of enhancement LU17483, which improves the performance of the ESP REST server.
This enhancement optimizes XCF communication from ESP to the REST server, leading to a significant reduction in CPUTime consumption for the REST server STC, depending on the workload.

A new initialization parameter, SCBDRATE, has been introduced to allow for the configuration of this enhancement. The optimization is enabled by default after applying the PTF, and we recommend keeping the default settings unchanged.


For more detailed information, please refer to techdocs.broadcom.com:

I think the link is incorrect, and should be LU17483

Hi David,

thanks for reaching out. You are correct, the link you are suggesting is better - LU17483. The one I originally gave was usable only internally for Broadcom.
I've updated the original post.
