I'm suffering from very slow viewing data of and ArcSDE database from an Arcgis engine application, the SDE database is in localhost so there's no network issues. but i still don't know the reasons neither how to solve this problem.
i'm working on 64 bit machine with 2 CPU's Xeon 3.4 GHz and 2 Gb of RAM.
the database contains 20 feature class, but with the max number of features do not exceed 100 000 in some feature classes, if i wait to view the data i should wait 10 minutes.
i tried to compress and rebuild indexes in the database but there's no improvements at all.
i tried to view data from ArcMap, i have founded the same problem.
Using the performance monitor i remarked some bottlenecks in CPU and network sides.
SDEINTERCEPT details:
i have tried @travis advice, so i opened mxd referencing data in sde with Arcmap, then i remarked this part take 7 minutes:

what could make ExecuteSpatialQuery so slow to take 7 minutes ?
I'm available for explanations of the problem.
Any help please.
Best Answer
I'm guessing you may have general performance issues such as labeling, layer scale rendering, transparencies..etc. If you have ArcGIS for Server license you may try using the Analyze button on the Service Editor to test a map document for these performance warnings.
Analyzing your GIS resource
You may then model your fixed map document layer configuration to use within your ArcEngine app to improve performance.
