Common theme running - speed issues during peak time

There seems to be a common theme running across the forum of peak time speed issues. This seems to be affecting both IPstream and LLU users.

In all the threads/posts relating to this it is during the period 16:00 - 00:00 that the speeds of various user's connections drops dramatically. Agreed that some of this may well be down to exchange contention on both IPstream and LLU, but it seems that it more than coincidental that the problem is occuring during the time in which profile management and traffic shaping occurs.

AFAIK I haven't reached useage limits yet, so shouldn't be affected by any of the level 1 management, and to the best of my knowledge souldn't be seeing profile management either, yet my speeds drop dramatically during this period.

Common theme running - speed issues during peak time

Hi,

This does look like a fault, I can't be certain exactly where at the moment, it could be a number of things. The ticket's with the faults team and they should be able to progress this for you and find out exactly what's wrong.

Ticket returned to me as having come back from Tiscali. A change in profile supposedly made. I did see the router synch at 4096 for 12 gours and then resynch back at 8157.

Off peak speed is as before fine and fast. Speed between 16:00 and 00:00 poor

Sent it back to faults again.

With the speed problem being during peak times, I still have to wonder if there is not a fault somewhere at the +Net end as it would seem that my speed is being severely restricted during peak times

Hi there,

Not entirely sure why you're seeing this kind of speed problem. If it were a generic issue I'd expect to see this across the board.

I'd suggest that it potentially point to a Tiscali hardware issue at the exchange.

Wouldn't have boticed it if OH hadn't moaned about the internet being dead slow or stop in the evening, for the little browsing that she does. Virtually all of my traffic is during off peak, mainly browsing and http downloads.

Let's see what Tiscali come back with this time, but it does seem coincidental that it is occurring during the times for profile/traffic management.

It's nothing to do with profile/traffic management.

As I said coincidental that it happens at the same time. O know it would be highly unlikely as I don't get close to the useage limits peak time.

Could always walk around to the exchange, would only take about 5 mins, and give their kit a boot up the proverbial Cheesy

I am sane, the voices tell me that :lol:

Yeah, I fully understand why you would come to that conclusion, but I have double and triple checked and can say with a high level of certainty, that it isn't the case.

I'll presume that you're talking about my profile and not my sanity James Cheesy

Now just to play the hunt the needle in a haystack game as I know there are a thousand and two different possibilities to be eliminated

Just an aside, did you know that http://plusnet.maxspeed.epitiro.com/ incorrectly reports RWIN values? According to this speedtester my RWIN is 5880. Checked and triple checked windows settings and it is 181000
