comment Optimising map cache creation performance in ArcGIS for Server 10.2.1
I think radouxju's comment was referring to disk I/O contention rather than permissions. The speed with which the processes can write image files could be the bottleneck.

comment How do I search dates using the ArcGIS REST API?
OK thanks for the info. I'm glad things have changed for 10.2 as expecting a service client to know the underlying architecture is ridiculous (and very 'ESRI')

comment JS/browser API library to show/interact with many markers with the best performance?
also "tailored for very high performance" implies that you don't think OpenLayers is already written to be fast. Mapping APIs is a competitive field and everyone wants fast

I have asked two relevant questions: gis.stackexchange.com/questions/19117/… and gis.stackexchange.com/questions/18572/…

comment Create base maps from vector data
In GeoServer you will create a 'group layer' which combines your separate 5 layers, then the user will request this. This will also be used to generate your tile cache

comment How did OpenLayers 3 managed to export map from other domain?
you're still describing something that is irrelevant in this question. The site referenced in the question does not use a proxy.cgi script. If you don't believe me please see: i.imgur.com/gFMrczn.png If a proxy was used the tiles would come from something like ol3js.org/proxy.cgi, but they don't - they come from an entirely separate domain. The question's poster sees this and understands this means the canvas is indeed tainted. Your answer and comments are relevant to different questions but not this one. One may therefore choose to describe the answer as 'incorrect'

comment How did OpenLayers 3 managed to export map from other domain?
I mean in this case you are incorrect. I'm well aware that the proxy approach works, but the referenced application doesn't use it.

I think this is incorrect. If you view the application's network traffic you will see the tiles being sourced from a different domain by the browser. No proxy is being used.

comment Is it possible to generate a heatmap on the server-side using ArcGIS Server?
generating XML can be extremely fast so the additional time required to generate the SLD really just depends on how long the database query takes to retrieve the data that the SLD is based on.

the SLD is a stylesheet that tells the map server which colour / size (if points) / border thicknes etc. to use when drawing features. You make one WMS request to the map server and that request includes some information about the SLD you want to use. The map server retrieves that SLD under the covers - which is generated dynamically to say either a) feature 1 is green, feature 2 is red etc. or b) population 0 to <= 1,000 is blue, population 1001 to <= 2000 is pink etc. - and then the map server renders and returns the image using those colours
