Обсуждение: performance optimizations?

do i need to worry about performance optimizations running the binary
distribution of cygwin postgresql? for example, do i need to worry
about setting the buffer sizes and shmmax and other such goodies?

if the performance can be optimized somewhat, is there a faq somewhere
correlating the performance notes for linux to cygwin?

thanks!

I don't think so, but I don't really know.  Maybe someone else on the
list can offer their knowledge.

However, you may be interested in the following:

Specifically, the remark regarding Cygwin vs. Linux performance:
