If I look at the characteristic of my computer here at CPDN, it reports, among other things Average upload rate 762.56 KB/sec Average download rate 15823.88 KB/sec Now, according to my ISP, my upload and download speeds are guaranteed to be at least 75 Megabits per second, though I have seen them as high as 85 Megabits per second. Also, my Network Interface card can go up to a Gigabit/second, but my router cannot. So how do they get 15823 KBytes/second download speed, which comes to 126 Megabits per second? Is something working remarkably well, or am I misunderstanding something? |

I have noticed the initial high speed and I assume it is filling up a cache in the router? |

I have noticed the initial high speed and I assume it is filling up a cache in the router? As far as I know, my router has no cache.. Status: Connected Network: Broadband Connection Connection Type: Ethernet/Coax MAC Address: ... IP Address: ... Subnet Mask: 255.255.255.0 Default Gateway: ... DNS Servers: 71.250.0.12 68.237.161.12 IP Address Distribution: Disabled Received Packets: 56803409 Sent Packets: 34986353 Time Span: 1990:02:30 My machine is this one: 1256552 It seems to me that these speeds are either the average speeds since this machine joined the project (1 Dec 2012, 10:10:08 UTC), or the most recent speed it has experienced. I.e., speeds not measured at my end, but the speed measured at the CPDN or Boinc server end. I assumed these speeds to be mainly the speeds that work units were downloaded to me, or the results uploaded to me; i.e., pretty big blocks |

not sure. Looking at my own computers the reported speeds are only marginally faster than when I do a speed test during the day. Probably because I have internet access set to an hour about three in the morning. |

These are the speeds of my recent speed tests (divide by 8 to get bytes/second) 10/4/2019 7:45:44 AM 83.98 Mbps 87.33 Mbps 100.35.165.125 New York City, NY 10/1/2019 5:17:42 PM 83.84 Mbps 66.32 Mbps 100.35.165.125 Seattle, WA 10/1/2019 5:16:50 PM 79.64 Mbps 65.05 Mbps 100.35.165.125 Los Angeles, CA 10/1/2019 5:15:26 PM 83.07 Mbps 68.83 Mbps 100.35.165.125 New York City, NY |
