I have published an ArcGIS service based on a MXD I have generated the cached tiles on a shared NAS. When I access the Map Service with the build in js admin viewer (http://SERVER/arcgis/rest/service/....)

The map display quickly but, every now and then no tiles are coming for maybe 5 seconds, and then they all come quickly.

Why could that be? Any tip / ideas welcome? How to diagnose the problem?

Lloyd, I believe we work together? Hit me up tomorrow on communicator and lets see if we can work it out and post outcome on here afterwards. Id be using Firebug and netmon to inspect whats causing the delays. –  Simon Jul 5 '12 at 12:29

On your web server, create a script that wakes your services up every 15 minutes or so. Below is an example of a vbs file that the Windows Task Manager runs every 15 minutes:

'declare web app variable, set variable to be an IE application
Dim webApp
Set webApp= CreateObject("InternetExplorer.Application")

'set visibility of the web app, can be set to false to run in the background
webApp.Visible = true

'declare a counter variable as integer, set it to zero
Dim counter
counter = 0

'declare array to hold names of different services
'simply increase the array by +1 and add a new entry for every new service that gets published

dim services(6)

dim map(4)

'the following loop uses the REST API and the array to step through each service page

Do while counter < 4

For Each x in services      
  webApp.Navigate "http://gisweb/ArcGIS/rest/services/"& x  

For Each y in map  
  webApp.Navigate "http://gisweb/ArcGIS/rest/services/"& y & "?f=jsapi"  

counter = counter + 1

Set webApp = nothing

That is a great tip Scott, lots of stuff about app-pools etc but that is a very nice yet brute-force route... +1 –  D.E.Wright Aug 13 '12 at 16:51
