What's the meaning of the ethereum Parity console output lines?

Question

Parity doesn't seem to have any documentation on what it's console output means. At least none that I've found which admittedly doesn't mean a whole lot. Can anyone give me a breakdown of the meaning of the following line?

2018-03-09 00:05:12 UTC Syncing #4896969 61ee…bdad     2 blk/s  508 tx/s  16 Mgas/s    645+    1 Qed  #4897616   17/25 peers      4 MiB chain  135 MiB db   42 MiB queue    5 MiB sync  RPC:  0 conn,  0 req/s, 182 µs

thanks
