--------------------------------------------

[~ckozak] Is not chunk size already configurable with  {{Http1Config#chunkSizeHint}}?

> Currently the default value is 2 KiB, which is relatively small as discussed in [https://github.com/apache/httpcomponents-core/pull/206#discussion_r462154831]
> Creating this ticket to discuss using a larger default value. The drawback to increasing the chunk size is that the chunk cache buffer is created for each request entity stream unlike the session buffer which is associated with a potentially persistent connection. This will result in higher allocation pressure for chunked request heavy uses, especially when the chunked request body may be much smaller than the chunk hint size. In order to work around this, the connection may create a reusable buffer based on the chunk hint which is reused across requests.
> Open questions:
> Should we increase the default chunk size?
> What value should we use?
