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.
