The SAS® Event Stream Processing Lua esp_publish function performs slowly when you use the logs=true option


A SAS Event Stream Processing project can use the Lua esp_publish function to publish events to a source window. If the esp_publish function uses the logs=true option, the function publishes events at the rate of ten events per second.  

This issue occurs after you upgrade to Stable 2025.11 or later.

Workaround

To circumvent this issue, use the logs=false option on the Lua esp_publish function. This workaround is needed for Stable versions 2025.11, 2025.12, 2026.01, and 2026.02. 

This issue is resolved in Stable 2026.03.
