Improve performance of reading HTTP headers
-------------------------------------------
Key: AXIS2C-1480
URL: https://issues.apache.org/jira/browse/AXIS2C-1480
Project: Axis2-C
Issue Type: Improvement
Components: transport/http, util
Reporter: nadir amra
Currently, in file src/core/transport/http/sender/http_client.c, when
processing HTTP headers, we read the data 1 byte at a time. This is too
inefficient and performance intensive, since each read means a read to the
TCP/IP stack.
The proposal is to improve the stream utility support so that one can specify a
minimum number of bytes to read. So that when a read comes down that is less
than the minimum, we read the minimum into a stream buffer and then copy the
requested read length into caller buffer. So next time stream is read, and
there is data in the stream buffer, the data is returned without having to do a
socket read.
We can probably extend this on the stream write-side as well.
