Kafka Stream KTable delay

As far as I know, Kafka Stream process the messages "as soon as it arrives". But when I use Kafka Stream for processing KTable (e.g. word count example on documentation, it has some delay (up to seconds) to group and show the word count to output topic.
Is this normal or any other configuration that I need to set?

If we set commit.interval.ms = 0, Kafka Stream will commit the offset as soon as possible.

Note, if processing.guarantee is set to exactly_once, the default value is 100, otherwise the default value is 30000 ms.

From the official Kafka Streams docs - https://kafka.apache.org/documentation/#streamsconfigs
