Dear All Experts,
I am using in PostgreSQL 8.3.5 database on windows 64 bit OS.
However, I have a batch program written in Java which processes the
data and populates them into tables in Postgres database.
I have *622,000 number of records *but it is taking almost *4 and half
hours* to load these data into the tables.
I have a simple function in db which is being called from Java batch
program to populate the records into tables from flat files.
I have the below system configuration for my database server.
Database Server
*PostgreSQL v8.3.5*
Operating System
*Windows 2003 Server 64 bit, Service Pack 2*
CPU
*2 * Quad Core AMD Opteron Processor 2376 @ 2.29 GHz*
Memory
*16 GB RAM*
Disk Space
*total 2.5 TB [C drive – 454 GB & D drive 1.99 TB]*
...
with one thread doing inserts, the other 7 cores will be idle. but
you're almost certainly disk IO bound.
OTOH, if you're calling a function (is that pl-pgsql, pl-java, pl-perl,
or what?) for each insert, you could be compute bound on that single
core. really depends on what that function is doing.
