Hi,

I see that sqlite3 can be very different in terms of run time.

$ time sqlite3 file.sqa  -Atv > /dev/null

real    0m3.259s
user    0m0.193s
sys    0m0.704s
$ time sqlite3 file.sqa  -Atv > /dev/null

real    0m0.148s
user    0m0.086s
sys    0m0.057s

# Then do some else briefly

$ time sqlite3 file.sqa  -Atv > /dev/null

real    0m3.853s
user    0m0.200s
sys    0m0.828s

$ time sqlite3 gncdhgncsym2htmlsqa.sqa  -Atv > /dev/null

real    0m0.172s
user    0m0.094s
sys    0m0.065s

file.sqa is of size 4.1G and 42282 rows.

Does anybody know why there can be such big differences in speed?

My testing machine is a MacbookAir.
