<p class="p4">> Do you have any idea as to why people recommend against many storages under</p>
<p class="p4">> a single Zeo?</p>
<p class="p3"><br></p>
<p class="p4">Seriously?</p>
<p class="p3"><br></p>
<p class="p4">Go back and read the thread.</p>
<p class="p3"><br></p>
<p class="p4">Seriously mate. The "why" is very vague. </p>
<p class="p5"><br></p>
<p class="p5"><br></p>
<p class="p6">There is nothing vague about the first reply to your question:</p>
<p class="p5"><br></p>
<p class="p5"><br></p>
<p class="p6"><span class="Apple-converted-space"> </span>"ZEO does not handle each storage in a separate thread, so you're underusing multiple CPUs if you have them. Multiple ZEO servers would also spread the open sockets among them. There could still be a leak, but it'd take longer to exhaust file descriptors."</p>
<p class="p5"><br></p>
<p class="p5"><br></p>
<p class="p6">Spread the storages across multiple ZEOs.</p>
<p class="p5"><br></p>
<p class="p5"><br></p>
<p class="p4"> </p>
<p class="p4">> Also can increasing the invalidation-queue-size help this if</p>
<p class="p4">> there is memory to spare on the machine?</p>
<p class="p3"><br></p>
<p class="p4">Invalidation queue size has nothing to do with this.</p>
<p class="p3"><br></p>
<p class="p4">Once again very well explained thanks.</p>
