Robert Newson commented on COUCHDB-1009:
----------------------------------------

Good comment, yeah.

My testing didn't show any compelling reason to increase this value, though, but at least this way it's not hardcoded.

> The couch_stream buffer is hardcoded to 4Kb.
> This value should be configurable. Larger values can improve write and specially read performance (if we write larger chunks to disk, we have higher chances of reading more contiguous disk blocks afterwards). 
> I also think it's a good idea to change the default value from 4Kb to something higher (64Kb for e.g.).
> Patch attached
