we just got a new dual processor machine and I wonder if there is a way to utilize both processors.
Our DB server is basically fully dedicated to postgres. (its a dual amd with 4gb mem.)
I have a batch job that periodically loads about 8 million records into a table.
for this I drop the indices, truncate the table, use the copy to insert the data, recreate the indices (4 indices), vacuum the table.
That is all done through a perl batch job.
While I am doing this, I noticed that only one CPU is really used.
So here are my questions:
Is there a way to utilize both CPUs
Is it possible to split up the import file and run 2 copy processes
Is it possible to create 2 indices at the same time
Would I actually gain anything from that, or is the bottleneck somewhere else ?
(perl is a given here for the batch job)
If anyone has some experience or ideas... any hints or help on this would be appreciated.
Thanks Alex
