Am I correct in assuming I'll get the best performance from my nginx+php setup if I: - set PHP's output_buffering to 4096 - set PHP's zlib.output_compression to On

You should turn PHP's zlib.output_compression off.

- set nginx's fastcgi_buffers to the same number of php instances, and to a size of 4k

No, fastcgi_buffers is per connection. For example, if

fastcgi_pass 8 4k;

then each FastCGI connection may use up to 8 buffers.

You should set fastcgi_buffers to correspond to a typical response size.

- set nginx's client_body_buffer_size to 4k

Probably, no. You should set it bigger, something about 64K or 128K to avoid buffering to tempoarary file.

- set nginx to gzip everything if the client accepts it

Yes.
