Calling Gary or Mark about Gruss refresh issue

[one click king]

My friend has a normal laptop and I have bought an Acer netbook.

We use the same connection and sit the same distance away. My CPU for Gruss is always something like 30% but I am not sure why that should make the difference.

I have no other bulky programs on this computer, it's purely for Grussing and the net. It is only 2 months old and has Windows 7 starter.

My auto refresh is 0.1 but the actual refresh is much slower than my friend's normal laptop, what could be affecting it? It's not security software. I thought for a while that API was sticky but sitting next to him proved that it wasn't.

I am quite computer literate, but this is something I cannot work out. Any ideas? Is my 1.6hz Atom processor the problem. I have 115GB left of 136GB

Are you using a wireless connection? To rule out an issue with your router try it on a wired connection without anybody else sharing the connection. I would expect the CPU to be higher than usual as it's quite a low powered CPU.

Hi Gary

We share the wifi and I don't think that is the issue, because his flickers much quicker. I will be able to properly test it again tomorrow and report anything that happens.

I've found my netbook, which has a similar processor to yours, pretty crap for almost everything I use it for. Its only got 1GB RAM and does nothing as quick as my other laptop.

I suspect that is the reason myself but a bit annoying if it is. I can use my other laptop but was hoping to use this one.

I am interesting to buy a netbook & I have no complains from my acer laptops.I would expect similar behavior from an acer netbook too, but as I see this not the case?

Is there someone that could suggest a decent netbook for gruss & net?

I have an Acer netbook with atom processor i bought only to use with BA. i found it often froze and no longer use it, waste of £220

Is there any good reason why they are slower. It seems a bit crap if you have a netbook for just net use and has no baulky programs except for BA, and it runs slower.


What are the key components needed for it to work at a proper speed? Is it really a processor issue, I thought it was purely working on an internet basis. Even so, a new computer with a 1.6ghz processor ought to be okay?

I've got an Advent and agree with Arnold, BA freezes at fast refresh rates. It's Ok if you have the refresh rate at 2-3 seconds.

[GaryRussell]

Sorry, I'm now going to ask the obvious question I should have asked in the first place. The default throttle rate is 10 requests per second. If you have set the refresh rate at 0.1 and have placed bets in a market then it needs to make 20 requests per second. Have you changed the throttle rate to 20 in preferences?

Hi Gary

Thanks for that advice, I will give it ago and let you know. My refresh is 0.1 and throttle is 10, so I will change the throttle to 20 and let you know how I get on.

Gary please explain about "throttle rate" and "requests" i didn't know you had to change your preferences when changing the refresh rate!! could this not be done automatically ?

[GaryRussell]

It's in the user guide. You can view the user guide from the help menu. Read the section titled "Request charges". Betfair requested that we make the default throttle rate 10, but you can increase it to 20 without incurring charges as long as you are not using any other API applications or the Betfair website.

You don't need to keep changing the throttle rate to change the refresh rate, you just need to be aware that you cannot achieve the fastest refresh without setting it to 20.

1. In theory with refresh rate at 0.1 sec and no placing bets what is the expected placed requests per sec ?
2. If the actual refresh rate at this case is lets say 0.2sec (instead of 0.1) the expected placed requests per sec are different now?
3. Is the 0.1 refresh rate achievable in practice? Does it need something special ? ( BA running from a server?). The best I get is 0.2 actual refresh rate. If I set it at 0.1 it seems that is exactly the same as 0.2.

[GaryRussell]

1) It's 10. Every 10th second there is an extra refresh to check if any bets are placed from outside of Betting Assistant.

2) It could be that your connection is not good enough or if you are using the ladder interface it also has to make an extra two requests for market depth and traded volume so you are not going to achieve 10 price refreshes per second.

3) Yes it is achievable on the grid interface with a decent connection. You don't need to be running on a server. The figure in brackets after the actual refresh rate is the response time. The closer this response time is to 100ms the less chance you have of achieving the maximum refresh rate as it will have less time to process the data and update the display before the next refresh.
