Hi,
i am using libpq library and postgresql 8.4 for my linux application running on ARM with 256 MB. I am just doing:
PQconnectdb();
PQexec(INSERT INTO table1 ....); (0.009661 sec.)
PQexec(INSERT INTO table1 ....); (0.004208 sec.)
PQexec(INSERT INTO table2 ....); (0.007352 sec.)
PQexec(INSERT INTO table2 ....); (0.002533 sec.)
PQexec(INSERT INTO table2 ....); (0.002281 sec.)
PQexec(INSERT INTO table2 ....); (0.002244 sec.)
PQexec(INSERT INTO table3 ....); (0.006903 sec.)
PQexec(INSERT INTO table3 ....); (0.002903 sec.)
PQfinnish();
I check the time for each PQexec with gettimeofday function and I always see that the first INSERT for each table needs longer than the next ones.
this must be something with the parser stage and since i am doing every time the same queries, I would like to know if there is a way to cache this queries in order to speed up the first INSERTs.
Thanks in advance,
Sergio
