Delay with photon objective c client.

Shakthi Prasad G S

Hi all,
We are trying to integrate photon objective c api in our iOS game.

We got values " 576 2000 162" for [mLoadBalancingClient RoundTripTime],[mLoadBalancingClient TimePingInterval], [mLoadBalancingClient RoundTripTimeVariance] respectively.

However with another game which uses photon unity network, RoundTripTime:90.

Did anybody try photon objective c APIs? How is the network performance?


Thanks

Hi Shakthi.

The round trip time and variance of the objC clients should be about the same as with the PUN ones.

Please check, that you connect to the same server address / cloud region with the objC client as you do with the PUN one. Please also check that you are calling service() frequently enough.

Hi Kaiserludi,

Thanks for the quick response.

What is optimum frequency of calling service. In my code its 10/second.
[NSTimer scheduledTimerWithTimeInterval:0.1f target:self selector:@selector(run userInfo:nil repeats:true];

The optimum depends a lot on your custom game logic.
You could try to set it to 20 times a second and see if it makes a difference on your rtt. If the rtt is still that bad, then it's not an issue caused by too few service() calls.

Changing service rate does not help
[NSTimer scheduledTimerWithTimeInterval:1.0/20.0f target:self selector:@selector(run userInfo:nil repeats:true];

Still RoundTripTime: 214

Kaiserludi

With calling service() 10 times a second you have had a rtt of 576, now with 20 times you have one of 214ms? Well, I would say, that it's definitely helping then, just 20 times still seems not to be enough in your case. Play a bit more around with that rate. 50 times a second would probably drop your rtt down to a value similar to the one that you have had in PUN.

I can't confirm that. Actually, its varying in a range 197-300

OK, what ping are you getting, when you are directly pinging the url to which you connect from the terminal?

Shakthi Prasad G S

Ping app-asia.exitgamescloud.com
round-trip min/avg/max/stddev = 111.298/264.921/406.982/68.746 ms


AVG 264 ms. Do you think problem with network?

Kaiserludi

So you have a ping of 264 without Photon, but your PUN client has a rtt of 90? Then your PUN client obviously connects to a different server address!

Shakthi Prasad G S

OK. I will recheck and get back to you.

Thanks,

We found service request WAS the issue.

Thanks for the update.
