High processing time usually means buyers are taking too long to respond to RTB ping requests. This can delay routing decisions and reduce the chances of calls connecting successfully.
Common causes include:
Slow buyer endpoints or APIs
Buyer servers timing out
Too many buyers in the RTB flow
Long timeout settings
Network or server latency
Buyers returning delayed bid responses
You can identify this in the Inbound RTB Statistics Summary under:
Processing Time
By Buyer → Processing (s)
How to improve processing time
Remove or pause slow buyers
Lower RTB timeout settings
Verify buyer endpoints are healthy
Reduce unnecessary RTB targets
Prioritize faster buyers with better response times
Lower processing times typically improve connection rates and routing efficiency.
