So you're already doing the smart thing....good....and I believe you did say you're using a memory database, right? Not storing it on the SD card?
Are you able to run your timing test on a standard PC? 50 inserts/sec is definitely NOT fast (that's your .02 number). Thousands/sec is more like it on a standard PC. Did you create any indexes on your data? Are you sure you have the entire load process in one transaction? Care to show us your code? Another thing you can do is output SQL statements to stdout so you can run those inserts inside an sqlite3 shell and test different configurations that way. Michael D.

Executing the same steps for all images (folder where all images stored ) in SD card . Total time to parsing and insert the 500 image =42 sec Time to insert one image in table after parsing = .02 Sec Time to parsing one images = .04 sec Cheers kritesh On Tue, Aug 28, 2012 at 9:22 PM, Black, Michael (IS) <michael.bla...@ngc.com > wrote: > I think the first thing you'll hear is to NOT store the video data in the > database. > Just store a file path.
