IBDAC extrem langsam (16 x langsamer als IBX)

Hier die Antwort vom Hersteller-Support (http://www.devart.com/forums/viewtopic.php?t=20112)

Zitat:

The CacheArray, CacheBlobs, DeferredBlobRead, and DeferredArrayRead options manage the way of working with BLOB and array content. If the CacheBlobs property is set to True, then local memory buffer is allocated to hold a copy of the BLOB content. If the DeferredBlobRead property is set to True, all BLOB values are only fetched when they are explicitly requested. To get the highest performance you should set DeferredBlobRead to True and CacheBlobs to True. In this case only requested portions of data will be fetched from the server. It's the same with the CacheArray and DeferredArrayRead options. For more information please read the IBDAC documentation.
