> Given the significant improvements on the service side over the past few years, the current client-side retry mechanism, which enforces 5-6 minutes of sleep time with jitter, is now excessive. Therefore, we are realigning the retry and throttling logic thresholds.
> Since the service can now handle higher traffic rates, we aim to enhance driver performance by setting the following configurations as default:
>  * {*}Client-side throttling (CST){*}: Off
>  * *Client Backoff* - 500ms (reduced from 3sec)
>  * *Max Backoff* - 25s (reduced from 30sec)
>  * *Min Backoff* - 500ms (reduced from 3sec)
