[core] server.chunkqueue-chunk-sz = 4096 

server.chunkqueue-chunk-sz = 4096 (default)
Can be configured any integral value greater than 0.
Value is rounded up to next 1024 if not an even multiple of 1k.

Sites with large request or response headers may benefit from
an 8k or 16k chunk size.  Embedded systems might choose to minimize
memory use by using a 1k chunk size.
