Some of the program flags: ``` -Xmx15120M --off-heap-ram=15120 --verbosity=progress --threads=30 ```

By looking at the output of pstree, I can see that there are 30 "pool" threads: ``` java(124002)-+-{AsyncAppender-W}(124029) |-{AsynchronousPro}(124146) |-{AsynchronousPro}(124148) |-{AsynchronousPro}(124149) |-{AsynchronousPro}(124150) |-{AsynchronousPro}(124151) |-{AsynchronousPro}(124152) |-{AsynchronousPro}(124153) |-{AsynchronousPro}(124154) |-{AsynchronousPro}(124155) |-{AsynchronousPro}(124158) |-{AsynchronousPro}(124159) |-{AsynchronousPro}(124161)...

(Previously, I ran this same command with 100GB of memory limit, but it wasn't honored, and it ended up exceeding the machine's total memory).

I left it running overnight, and memory didn't grow beyond 82GB, but it looked like it wasn't making any progress: there were still 6 queries running, but only one core...

Hi Lucio, Thanks for your answer! That solved the issue :). It took me some time to find the right documentation and understand how to use it. Maybe it would...
