I'm looking for suggestions on improving performance of my sqlite application.
Here are system timings for a run where the sqlite db has been replaced with a flat file output.
real 0m1.459s
user 0m0.276s
sys 0m0.252s
This is a run when using sqlite as the output format.
real 0m3.095s
user 0m1.956s
sys 0m0.160s
As you can see sqlite takes twice as long and almost 8 times the user time.
Output size for flat file: 13, 360, 504 flatfile.dat
Output size fo sqlit file: 11,042,816 sqlt.db f
Slite db has the following pragmas set.
PRAGMA default_synchronous=FULL
PRAGMA temp_store=memory
PRAGMA page_size=4096
PRAGMA cache_size=2000
Any ideas how to get the sqlite output timings to a more respectable level would be appreciated.
Thanks
Ken
If you want flat file performance, use a flat file. Sqlite is built on
top of a flat file and cannot be faster or even as fast. If your
application can use a flat file, why use anything more complex?
