Location: Bryan, Texas                We did an informal load test today of a 
real site (that we are about to launch) with about 30 simultaneous connections 
from people all over the place. We have (5) web apps running in "stand alone" 
mode behind Nginx as a load balancer and handling SSL. We did not have near 
enough users testing. My guess is that (1) standalone web app could have 
handled the load just fine. Once we go live, we might have as many as 100 users 
simultaneously. We just want to have plenty of capacity in case there is a 
spike in usage. Informally, I would guess that the configuration we have would 
support at least 100 users at a time. 

Several "testers" reported issues and it seems to be their internet connection 
and nothing necessarily in the RealStudio Web App.

 "Bad Experience" Users:

#1 He was using a laptop connected to his network with a wireless router on a 
dsl connection. This user said his internet was fine most of the time. But when 
using the WE site, he got lots of pauses, lags and delays but it was still 
usable.

 #2 She was in my office using an iPad on our wireless router. Our internet 
connection runs at 50Mbp. I tested the website on her iPad. It was extremely 
slow and unresponsive, barely usable. When you click a button you can wait 
about 30 seconds and if nothing happens you can continue clicking and it will 
eventually respond. Sometimes the next few clicks will respond then it will 
start to "hang" again. 

Is this an iPad issue?

Is there anything, programming wise, we can do to help either situation above?

Thanks,
Brandon

Was the test site in the office or hosted elsewhere? Were other sites loading 
fine on the iPad? Wireless networks can have many issues on their own that 
affect latency and bandwidth. There's really not much info to go on here to 
help you. Since the iPad was on your network you could put a capture tool 
somewhere on the network and do some traffic analysis if it comes to that.

First thing would be to do some basic troubleshooting and post your findings if 
that doesn't reveal the problem.

Location: Bryan, Texas                Thanks for the response kevo. The site is 
hosted elsewhere on a vps. I did not test the ipad on other sites...should 
have. I guess I was just wondering in general...are there known issues with 
ipads and WE sites? Are there programming techniques with WE to help "hide" 
latency issues? I suspect the answer to #2 is no.
