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 these queries in order to speed up the first INSERT.
