Edit feature slow performance first time

[RodrigoFelga]

I have the following scenario:

A MXD containing about 60 layers divided in 5 featuredatasets, 2 of that datasets is registered as versioned.

The MXD is published in Arcgis Server with the Resource os MapServer and FeatureServer enabled. The servevice is configured with a maximum instances of 10 and minimum of 2. When I start, the service starts with 2 instaces "up" and I have no problem showing the map but when I try to edit a fetaure the first editing operation takes about 90 seconds to run (the service show that 1 instance is in use on ArcGIS Server Manager). The followings editing operations performs normally taking about 2 seconds to execute. This problem occurs only when edditing a feature with this featuredataset registered as versioned, with non versioned always runs fast.

My question is: Why this delay on the first operation if the instance is already running? Its possible to solve that?

P.S.: Sorry for my poor English.

Rodrigo,

  What version of ArcGIS Server are you using?

ArcGIS Server 10.5

Rodrigo,

   I am not real sure what your issue is,

but what are your services settings for 

Specify Recycling Settings

Recycling shuts down the process and restarts it at regular intervals to help maintain performance and stability.

and

Specify Health Check Settings
Periodically check and repair data connections for idle instances
Check and repair instances every:

Recicle every 24 hours starting 4:30 am

Check and repair instances every: 30 minutes

Rodrigo,

   I recycle my high demand service every 6 hours.

Hi Robert, I will change this setting but I don't think that's the problem decause the problem occurs the first time I try to call applyedits after the service is started, the others calls is ok.

Hi Robert, the problem continues. Any other advices?

[RobertScheitlin__GISP]

Rodrigo,

  Could be something like this. I am not sure which enterprise DB you are using though.

SQL Server Wake-up

Thanks for your reply, I'm using oracle 11g and the problem only occurs with versioned datasets. I will send this to ESRI to see if they have a clue (I doubt)
