Anyone in here good at reading packet captures & finding troublesome

We have a location that complains from time to time that 'the network
is slow'. We ran a packet capture over there for the better part of a
day to see if we can find anything.

Trying a couple different demos of software that helps break packet
captures down to be easier to read, I just don't fully know what I'm
looking at with this stuff.

Anyone willing to look at one of these captures & see if anything jumps
out at you as far as something causing network issues?
