Question

Does anyone know if you take a performance hit calling CloudConfigurationManager GetSetting method? Does it reparse the azure file for example or is it cached? Not sure if I should add my own caching/static variable to improve perf for something called often like a connection string.

Thanks

The source is available on github.

If you take a look at the source you can see that it isn’t doing any caching, so if you are seeing performance issues you may want to implement your own caching.

The body of GetSetting shows a simple return:

value = GetValue("ServiceRuntime", name, GetServiceRuntimeSetting);

if (value == null)
{
    value = GetValue("ConfigurationManager", name, n => ConfigurationManager.AppSettings[n]);
}

return value;
