SpeedTracer NETWORK_RESOURCE_RESPONSE vs NETWORK_RESOURCE_FINISH
- by Ben Flynn
I'm using SpeedTracer with GoogleChrome to measure the load times of requested resources.
The SpeedTracer site says:
NETWORK_RESOURCE_RESPONSE "Indicates that the renderer has started receiving bits from the resource loader"
NETWORK_RESOURCE_FINISH "Indictes a resource load is successful and complete."
In my mind that means we would always see a network resource response (bytes are arriving) before we see a finish (all bytes received). This doesn't seem to be the case at all. Here is a sample:
Request Timing @33519ms for 926ms
Response Timing @34445ms for -847ms
Total Timing @33519ms for 78ms
I'm guessing response time isn't supposed to be negative. Can someone explain this or is this a bug? I'm using Chrome 10.0.612.3 dev with a SpeedTracer I downloaded today.
