Increase the idleTimeout to 15 seconds to enhance API response time.

[nahidmk]

Request Statement

I want to improve the response time of my API call. When I hit an API using Postman, it takes only 80ms, but the same API takes 250ms in Flutter Dio. Some people suggested me to increase idleTimeout to 15 seconds to improve API response time. I have changed idleTimeout from 3 seconds to 15 seconds, and it actually improves the API response time. So, does it cause any problems to increase idleTimeout to 15 seconds?

Which idleTimeout?

[nahidmk]

inside the io_adapter

HttpClient _createHttpClient() {
if (createHttpClient != null) {
return createHttpClient!();
}
final client = HttpClient()..idleTimeout = const Duration(seconds: 15);
// ignore: deprecated_member_use, deprecated_member_use_from_same_package
return onHttpClientCreate?.call(client) ?? client;
}

In the code you referenced, you can always specify the idleTimeout when using createHttpClient.

[nahidmk]

"This is the code from Dio's repository located at "lib/src/adapters/io_adapter.dart".

It was initially written as:
final client = HttpClient()..idleTimeout = const Duration(seconds: 3);

I changed it to:
final client = HttpClient()..idleTimeout = const Duration(seconds: 15);

Because of that, I have improved my API response time. So, why didn't the Dio team make this change?"

Improvements are related to use cases. Your use case might fit the 15 seconds idle timeout perfectly, others might not. Generally, changing such configuration will break users code, no one want that happen. Also, as I stated above #2046 (comment), there is no need for you to change the source code. Instead, set the createHttpClient to create your 15 secs timeout client.

Closing as we've already provide such ability.
