   > > Hi, I've been following this with great interest. Bringing native HTTP/2 
support to JMeter would be fantastic. May I ask how the asynchronous/parallel 
execution of HTTP/2 samplers will be handled? Will there be a new native 
controller?
   > > Thanks.

   > Thanks for your interest! HTTP/2 support uses the existing **HTTP 
Request** sampler; it doesn’t introduce a new controller.
   > 
   > A sampler still runs synchronously from the test plan’s perspective, so a 
JMeter thread waits for its response before moving to the next sampler. The 
HTTP/2 client uses asynchronous I/O underneath and can multiplex requests that 
are already concurrent—for example, embedded-resource downloads when concurrent 
downloads are enabled—over one connection.

   > It doesn’t make separate samplers run in parallel; that would be a 
separate feature.
   
   Hi @andreaslind01. Thanks for the response. Being able to run samplers in 
parallel would be a key requirement for many I guess. We serve microservices 
via apollo/graphql in parallel to the browser. Do you know if this separate 
feature (i.e. a native parralel controller) is in the pipeline? Again, thanks 
for your reply.
