Latency issue grows by number of workers On Start, improve the cost of first query

[Opensourcecommunitydevelopment]

improve the cost of first query
On Start the first query is slow because delay of worker Connection waiting created, so do it After init instantly and keepalive to be ready for querys.
Or workaround with a Pseudo query / HTTP2 WritePing To establish Connection directly After worker starts within the for worker Start loop!

Connection TLS Handshake RTT latencys

do Not Push query To worker that is Not ready!
may ping them every 5 minutes to verify they Are still alive and actually WORKING waiting for work (query.)
