Rendimiento lento de ArcGIS Online para uso en clase

Question

<\/HEAD>¿Alguien más nota que ArcGIS Online funciona lentamente cuando toda una clase lo está usando? Tengo entre 60 y 80 estudiantes de pregrado trabajando en un ejercicio establecido, es decir, todos están realizando las mismas operaciones con los mismos datos de entrada. Hemos encontrado que los buffers tardan más de 10 minutos, a veces mucho más, cuando para mí era menos de un minuto al configurar el ejercicio. Como pueden imaginar, esto es muy frustrante y está desanimando a los estudiantes a usar el servicio en el futuro.<\/P> <\/P> ¿Es este un problema conocido y, lo que es más importante, hay algo que podamos hacer para acelerar las cosas?<\/P> <\/P> He intentado que los estudiantes guarden sus propias copias de las capas de entrada antes de ejecutar los procesos de análisis, y parece que no ayuda.<\/P><\/BODY><\/HTML>

Katy - did you ever figure this out? I'm seeing a similar thing...

Apologies for the delayed reply due to the festive break. I raised it with Esri UK support who said much the same. From subsequent classes it does seem to be a local network inadequacy, as a couple of students running their own laptops at the same time, using the wireless network, saw no slowdown. Only those using lab desktop machines on the wired network were affected.

I will pursue with our local IT, but I expect more questions from them about the typical traffic generated, which UK support have not answered. What I am not sure about is the traffic flow for running something like a buffer. I (naively) assumed it was something like: the command is sent from the local machine, the tool runs on a server somewhere using the input also held in the cloud, creates the output in the cloud and then that output is delivered back to the local user. In that situation the only network traffic is sending the command and receiving the output, which seems trivial (the layers are very simple), so I don't understand the slowdown. There must be more to it?

I'm happy to accept it's not an AGOL limitation, but it would still be useful to know if anyone else has experienced the same and seen it resolved through network infrastructure improvements.

We have not typically seen this reported and ArcGIS Online averages tens of thousands of users an hour. It could be something within your internal infrastructure? Let's investigate this further by contacting Esri technical support.
