On the PC client by pressing ^Z you get the Performance Indicators. I cannot track down any documentation on what they mean.
My guesses are
fps = frames per second
pkR = % loss of packets received
pkS = % loss of packets sent
ping = round trip time in ms for a ping to server.
pyS = ping something Server?
pyC = ping something Client?
msg = messages sent per second
pend = number of pending messages ?
(0.00 sec = ??)
Can a Dev please add some clarity to these metrics. I hate not knowing what they mean.
This piqued my curiosity, so I did a Bing search (I don't "Google"). Based on what I found, the "py" stands for Python (programming language): pyC is a compiler & pyS is an interface for Apache Spark in Python. Assuming any of this is correct, it still doesn't explain what the numbers mean, or what would be considered good or bad performance. Hopefully, a Dev or experienced programmer can explain.
