The buffer size appears to have doubled since the last release--I was running with NBUF=1000 in A/UX 1.1.  Should NBUF be increased?  Do you have any tuning suggestions?</FONT></div></div> <!--  attr Symptom  --></div> <!--  truncate --></div> <!--  intro-container --><div class="clear"> </div>

  <div class="attr SUMMARY">
<TT>In A/UX 2.0, the default NBUF value is 10% of the available memory after A/UX<BR>
is booted, and the SBUFSIZE now is 2048 instead of 1024. The value of NBUF can<BR>
be adjusted to fit your environmental needs via the &quot;kconfig -n /unix&quot; command.<BR>
Increasing the number of buffers reduces the memory available for applications<BR>
and may cause more paging.</TT></div>
