The oscillation is related to buffering and is normal. If you are getting |
17 |
longer stalling periods where no packets are being transmitted then there |
18 |
could be a network problem. iptraf-ng, ntop and other tools can show if |
19 |
packets have stopped moving in either direction. |

From what you're describing the problem seems related to the squid |
22 |
application, since scp is not seeing similar timeouts. |
