Can someone suggest some appropriate initial configuration parameters and
shared memory settings for the following hardware?
I'm running Debian on a Dell with 4x6 core CPU and 128GB memory and writing
to a coraid with 9 x 32GB SSDs RAID 10 using jfs with 8 drives active and 1
as spare.
I'm considering changing to xfs. I'm not sure what block size to use for
the file system, is 8192 appropriate? The OS page size is 4096.
The database is both write and read intensive, with about 750MB of new data
added per week and old deleted every six months to one year.

A good start:
Tuning: http://www.westnet.com/~gsmith/content/postgresql/pgbench-scaling.htm
Benchmark: http://edoceo.com/liber/db-postgresql-benchmark
Here's my benchmark on `m1.medium` instance of Amazon EC2:

Good luck,

Anh,
Were you using a EBS device in EC2 for that benchmark?
