## ISP load balancing
sometimes you might notice:
1. right after you establish udp2raw connection, the packet loss is high or latency is high
2. if you restart udp2raw with some chance it becomes significant better
this is not really udp2raw's fault. This is by ISP's load balancing mechanism, sometimes you are accidently allocated to a bad link.
#### workaround
you tried to restart/reconnect udp2raw for a few times, either by kill udp2raw or by the `--fifo` option, until you believe it's good enough.
## ISP punishment for long-term connection
sometimes you might notice:
1. right after you establish udp2raw connection, the packet loss and latency is good
2. after a day, you came back you see the packet-loss or latency becomes super bad
3. if you restart/reconnect udp2raw, it might recover.
#### workaround
when this happens, you can manually trigger a reconnect with the `--fifo` option.
It's better you write a script doing this. You monitor the packet loss of udp2raw via some script, if some condition is met your script tell udp2raw to reconnect with `--fifo`
