What is Response.timings.blocked indicates? And why call is blocked?

During the performance test run, I can see some of my requests are spent some time in block state. So in general what is the blocked state and why my requests are blocking?

Hi @ankurpshah,
as explained in the documentation for all the different http metrics this is the time that k6 waiting for a free TCP connection slot. This measures the time between when we’ve asked for a connection to when we actually received one.

I don’t know exactly what could cause that to be higher, but I would expect if it’s high that you are also CPU bound or something like that.
