[1.1.6] UPS drop from 60 to 20 (or lower) when placing Rail/Chain Signal

Hello,
Whenever I place a Rail or Chain signal on the map, whether it is connected to my primary rail grid or not my UPS tanks. One signal will easily take me below 40 UPS. Place a row of signals and I can go below 20. Build an intersection with bots and my computer practically melts for a few seconds.

My apologies I've included two screenshots. 1 of normal performance and the 2nd with the significant performance drop issue.

Even worse when I deconstructing them all at once:

I figured it out. I was missing a rail piece in one of my copper mines which caused 10 different trains to have a "no path" error. Everytime I placed a track they were trying to see if they could path again. Once I fixed the rail piece so they could path, the issue I experienced with signals disappeared.

Unfortunately when rails or signals are created or destroyed, there are many cases that may invalidate some train paths or make some trains to now have a path so they have to be checked and this causes increased update time.

Is it intended that this shows up under both train pathfinder and entity update? I guess I could see either, I'm kind of surprised it's both though.

Nothing unusual. Rail signals were placed by construction bots which happens during entity update, and placing signals causes immediate repath events or path revalidations for some trains.

I guess it makes sense from a technical perspective, I'm not really sure how else it would work. I was probably just expecting it to all add up to the total, so that might've thrown me for a loop. Anyway, thanks for the answer.
