Graph is representing TTLB (time to last byte) because it uses JMeter's Response time

If you want TTFB (time to first byte), you need to use Latency

JMeter measures the latency from just before sending the request to just after the first response has been received. Thus the time includes all the processing needed to assemble the request as well as assembling the first part of the response, which in general will be longer than one byte

If you want to display TTFB, a trick could be to replace latency with response time columns values and then display values in graph

In JMeter :

  • response time is Time To Last Byte (TTLB)
  • latency is Time To First Byte (TTFB)
