Hi,
I've a program made using gcc/C++ compiler (with Win32/dev-cpp) and an
ready-made sqlite3 lib using v3.5.6.
I try to optimize my code, and the gprof tool give me :
Each sample counts as 0.01 seconds.
% cumulative self self total
time seconds seconds calls ms/call ms/call name
25.19 224.40 224.40

5.50 451.70 49.00 sqlite3_blob_open
3.13 479.62 27.92 BZ2_decompress

...
Of course I never called sqlite3_enable_shared_cache() in my source code
:-) .
Any idea how to reduce this function call and the time spended in it.
Regards,
