When Webroot cloud lookup is enabled and the BIG-IP system is under stress load with URLs that cannot be categorized by the local Webroot database managed on the BIG-IP system, the TPS of the data path traffic slows down as it gets throttled.
The TPS Throughput may be reduced when this condition persists. This only occurs when Webroot cloud lookup enabled. The Webroot cloud lookup features is disabled by default.
If Webroot cloud lookup is enabled while there is heavy traffic with URLs that cannot be categorized by the local Webroot database managed on the BIG-IP system.
The system now throttles URL cloud lookup requests when PEM detects that the number of URLs that requires cloud lookup exceed TMM limits/thresholds.
