That is 32*8=256KB of memory. I thought default was 64. How much physical 
memory you have?

I suggest you set it up something like 256 to start with. That may be too 
small as well but you haven't provided enough details to come up with a 
better one.

Read postgresql.conf and admin guide about runtime parameters. You need to 
tune shared buffers and effective_cache_size at least.

Search performance archives about tuning these two. There is lot of material 
to cover in a single mail.
