Hello,

	I'm trying to route a big PCB. Schematic contains more than 200 pages
(it's a special sensor with more than 140 lines and 100 columns and each
sensor line takes a page.).

	I can create a netlist without any difficulties, but pcbnew is totaly
inusable. I have tried Kicad 5.1.5 on Linux debian and 5.1.4 on NetBSD 9 with same result. NetBSD's version of kicad comes from pkgsrc. Linux'one
was built with release flag (not débug).

I have opened pcbnew and opened netlist. And pcbnew takes 100% of a CPU
for more that 3 hours :

PID USER       PR NI   VIRT    RES    SHR S  %CPU  %MEM   TIME+ COMMAND
86423 bertrand 20 0 1660688 556144  84336 R  99,5 3,6 270:23.64 kicad

Workstation has 16GB of RAM and doesn't swap. Netlist only contains 678
components.

	I have tried to open netlist without DRC, same result. I don't
understand why pcbnew doesn't like this kind of netlist. In the past, I
have routed some PCB with more than 600 components without any diffculties.

	Any idea ?

	Best regards,

	JKB
