Some lags with GC via WideFS

[Jan Pemöller]

Hello,

since some weeks I have many lags when ASV/ASA (Active Sky Advanced) building new clouds. On the FS (FS9) maschine with 30 Frames I cant see any lag. I only see it on the GC which stopps for 2-4 sec. this happens every 2-5 min, when turning more often, on cruise it is more less.

Any idea to tune up the network or wideFS.

Thanks
Jan

P.S havent changed anything on my network! And it works very well before. It must be something with the comunication via WideFS. Are there any secret adjustments?

Hi

It sounds like something is not getting enough resources. I would be sure that the Server is not over-loaded, possibly capping your frame rate more. And if the problem resides on a client, then enable the GC limiter in the ini file and / or add a user defined limiter.

Apart from the above, it is needed to be sure that the network is configured correctly, and I would point you to the PM and better still the WideFS docs in this area re advice / tips on network settings. Even if you have already been through them, I myself find it a good idea from time to time to re-go through it all to check things.

this is the key:

Go to control panel -> system -> hardware tab -> Device Manager

Find the entry for Network Adapters, right click on the LAN adapter and select Properties then Advanced tab

In the Pro/100 VE there are way more than the usual 3-5 settings available. It includes Adaptive Technology, Adaptive Transmit Threshold, Coalesce Buffers, PCI Bus Effeciency, and Transmit Control Block parameters, all of which effect data store-and-forward and coalescing. In the case of this adapter, setting Adaptive Technology to 0 turns out to be the magic bullet that turns it all off.

The symptomology that will be present is a choppy flow of data...in one or possibly both directions...and significant lag and jitter in the data stream.

Thanks Bob ....

Best regrards

UPDATE:

to FIX this problem totaly:

- changed network to UDP Protokoll
- enable on all network-cards the "auto-detect" for the transfer speed (do not leave it on 100Mbit FullDuplex)

these two points are very importend !!!
