To really help it would be nice to know the hardware specifications you
are working with:
CPU type and number.
RAM
Storage subsystem
Also some indication of what the load on you system as whole is. Cannot
remember what your OS is, but information from something like top and
iostat. The reasoning being that fooling with connections may not be of
much help if the system is running at its max limits already. In other
words it is possible a hardware upgrade is what is needed.
