Measure Time to First byte in JDBCSampler #211
Conversation
- Use connect time to instead of latency to measure connection time - Use latency to measure the time at which the first ResultSet (or whatever) is received from the connection

I'm not sure the failing build is related to my commit. I had the error before my change. |

There was a problem hiding this comment.
The javadoc could (should) have documentation for the params, return value, ...
It looks a bit strange, that execute(conn) throws UnsupportedOperationException, but this method does not.

The SNI test is quite flaky, but as you suspected, that is not your fault. |

Hello, do you know why I'm not able to retrieve log apache dependencies ? ant download_jars is successful and ant install too. Is the issue related to IntelliJ? Thanks |
…dEncodingException because the IOException is more general. Add javadoc for execute method taking a sample as argument.

Hello, I couldn't figure out whether the job fails because of my changes or not. Any idea? Thanks |

The jobs fail because of the flaky sni test. They are not your fault. Thanks for the contribution. |
Hello,
I use JMeter to measure performance of a database. When executing queries returning a lot of rows, the time taken by JMeter to read the ResultSet and storing the result in a StringBuilder then calling toString() might be bigger than the execution time on the server.
In order to easily understand what's taking time for slow queries, I thought it might be interesting to use "Latency" and "Connect Time" of the SampleResult to show two informations:
What do you think of that change?
