TCP Sampler: Skip read response
Is there some way to configure the TCP Samplers that come with JMeter to
completely skip read response (reading from OutputStream)?
Current implementation as of version 2.10, after writing something it waits
for a response, reading data until the defined EOL byte is reached, or If
there is no EOL byte defined, it reads until the end of the stream is
reached.

This does not seem worth the effort unless there are other use cases
for the behaviour.
Also, as you have indicated, it's quite easy to create ones own
sampler that provides the required behaviour.

I am performing load on a server that has this behaviour. The clients only
perform writings and do not expect nothing in return (there is nothing to
read)
If we try to read something from output stream, there is nothing there; it
will block until some timeout happens; that's what's happening when i use
the TCP Samplers from JMeter. There is no eol byte, no end of stream,
nothing!
Reusing existing samplers on JMeter, I have implemented a new sampler that
simple extends the TCP Sampler implementation from JMeter overriding the
read operation/method in order to skip read on the OutputStream. This works
with the server I am performing load testing.
We could have some option for TCP Sampler base implementation that comes
with JMeter in order to skip the read on OuputStream.
best regards,
