Weird speed test reuslts on

Hi everyone,

Wondering if anyone else has ever seen speed tests extremely lower than what is set for customer.  We have a 30mbps down service and on it tests at 4mbps.  Iperf shows that the customer is getting 30mbps down... just getting tired of customers calling saying "I'm not getting the speeds Im paying for"


No - we haven't experienced that.  For example - here is a throughput graph a Force300 client who is on a 60 Mbit plan, and he pulls that all day long.

How was that traffic generated on that graph?

That is just the client using his internet.  I think he said he downloads files from NewGroups... so probably porn?   ;)  (LOL)

BUT, this isn't generated - it's not a speedtest or a bandwidth test or anything artificially generated. This is just MONITOR -> THROUGHPUT CHART when this client is using his 60 Mbit internet plan.  So that's really what he gets while using his internet.

Check MONITOR> performance & % of  retransmissions from both sides.

PS - We also do speedtests to several different speedtest servers when we install a customer... basically to show them it's working at their expected rate.  Especially if we're upgrading from one of our Legacy equipment plans, or if we are upgrading from a competitor.  THEN it's even more important for us to do a before/after with their old plan (or their old ISP) and we take screen shots for the customer profile 'album' so that the installers can document what the signals and performance is on install day.  We also do a 'wide open' test before we QOS it, to make sure we can see that everything is working correctly.

We tend to test to 4 different servers:
1) Netflix's '' and 2) '' and 3) our internal '' and 4) the Telco's Ookla.

This does take an extra 15-20 minutes or so, but it's good to show them that different servers in different locations can give different results (to let them know that not getting their QOS speed from every single point in the known universe might be distance, hops, or might be some link BETWEEN us and the remote server.. and not necessarily inside our network.
