I made some code rework:

https://gist.github.com/denizzzka/124dc3827a10d29dd04cb7331f4c4ff8

Previously there a pool of connections was created for each 
worker - this is unnecessary, it is better when the pool is 
common for all workers.

Also, I added PREPARE, row-by-row read for /normal (just for 
check if it helps) and replaced "id" by [0] on column accessing 
code

Nothing really helped

My measurements:
