I'm suffering from very slow editing in SDE from an Arcgis engine application, the SDE database is in local so there's no network issues. but i still ignore the reasons neither how to solve this problem.

i'm working on 64 bit machine with Intel i5 2.4 GHz CPU and 6 Gb of RAM.

the database contains 20 feature class, but with few few features the max number of features do not exceed 100.

I edit using an mxd file which contains sde feature class references, this mxd file is referenced by the Arcgis Engine app, in code level i follow these steps for every editing:

• start edit session and operation.
• insert feature using Featureclass.Create() method
• stop edit session and operation.
• refresh the actiview.

These steps tooks from 2 second to 4 seconds. sometimes the refresh could take 5 seconds, may be because i have some labelings , but compared to ArcMap it must run very fast.

I'm available for explanations of the problem.

Any help please.
