kdb+ multithreaded input mode

Hi

I have 8-CPU machine. I started kdb+ with negative port, it entered multithreaded input mode.

I issued 8 requests to this server, and they are all being processed (basically, loops that simulate delay).

I launched 9th connection to this server with “2+2” request, and it waits for any previous query to complete first, before entering .z.pg

Is it by design? Can this number (8) be changed? How come?

Thanks.

Which version/release of kdb+ are you using?

Since kdb+ 3.6 2017.10.30, multithreaded input queue mode no longer locks around accepting new connections.

Oh, yes! It works better on 3.6.

Thank you.
