Speed up WAN client <-> server connectivity

Cowmix · Post by **Cowmix** » Sat Mar 03, 2007 10:39 am

When using the DataStage 7.5.1.a Designer over a T-3 (45mbit/sec) link seems several times slower than using Designer over a local LAN. For instance, the initial login takes about 35 seconds over the WAN link while it might take 4 seconds over the local link.

Anyone have any tips on how to speed things up?

WAN's will be slower than LAN's. Thats a limitation from your WAN service provider. Can you watch streaming videos without any pause in them?

Throughput is great (1500 Kbytes/sec) in both directions. The ping times are right (31ms).

What's the ping time on your LAN? What does that say about relative speeds?

<1ms

Can anyone tell me their 'wan' login times?

WAN is extremely slow. You need to have your network admin monitor a DS client traffic on the network coming from your connection. You have to open a job, open/close a few stages, etc. It's staggering because the fat client has sooo much traffic.

I have customers who have users worldwide, they ultimately choose a remote-desktop-computing or terminal services type model to have DS clients run on the LAN where its much faster. The net gain works in your developers favor.
