Hi @colinrippeyfinarne ,
Please refer to article Azure Storage performance targets for details on the performance, scale and throughput for various scenarios. According to it, the expected maximum throughput for "External Event Processing" is "50 events per second, per instance". This is when using the Azure Storage as the storage provider for durable functions. There are other storage providers also available but in preview, which have shown better results as well. More details available here: Durable Functions storage providers
