<div>Hi,</div>
<div> </div>
<div>Here, we are using the recommended value and it is going OK:</div>
<div> </div>
<div> thread_pool_max 5000 [threads]<br /> thread_pool_min 5000 [threads]<br /> thread_pools 2 [pools]<br /><br /></div>
<div> Total Requests ~ 5k per/sec</div>
<div> </div>
<div> </div>
<div>Some times, the problem is the S.O tunning. </div>
<div>Now, it is receiving "Total Requests": 1266.83</div>
<div> </div>
<div>and Network is OK, but it could get busy:</div>
<div>$ ss -s</div>
<div>Total: 3516 (kernel 3654)<br />TCP: 50734 (estab 3319, closed 46718, orphaned 669, synrecv 0, timewait <span style="color: #000000;"><strong>46718</strong></span>/0), ports 139</div>
<div> </div>
<div> </div>
<div> </div>
<div>ps. I've alredy received these answers. Something happend and BOL re-sent this message.<br /> <br /><br /></div>
<div> </div>
<div>Thanks again.</div>
<div> </div>
<div> </div>

<div dir="ltr">Are there any exceptions to the "2 is best" rule for this? I'm asking out of curiosity. It seems strange to me that Varnish would even provide the option to change it if any other value is detrimental to performance.</div>

<div dir="ltr">That is correct. We haven't been able to see any increase in performance when the number of pools is increased above 2.</div>

<p class="MsoNormal">Hi,</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">By the book, the thread_pools should be 2. However the server is multi-processed(8 cpus) and can handle more thread_pools.</p>
</div>
<div>
<p class="MsoNormal">This server handles more than 5000 requests/sec.</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">Is it a good ideia increasing the thread_pools to 8 and decreasing the thread_pool_max?</p>
</div>
