I am trying to cluster my table faster. The table is 27 GB worth of data, and has one index using a point geometry which is 19 GB in size. I am seeing about 5.5 hours to cluster the table.
I am assuming clustering is a IO heavy process, so anything to improve read/write times (new disk) would be my first thought, but are there any other things that could improve the time it takes to cluster a table?
I ran this test on a machine with an SSD and 12 GB of RAM, using postgresql 9.4
