<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:12.0pt;font-family:"Times New Roman","serif"">how many items you will have in the hash table, or in other words, how big is the average size of in item in the hash table?<br>
<br>
Performances can be improved by adjusting the number of slots.<br>
<br>
Another thing to consider is the loading in cache, when kamailio is starting. It can take long when it is a really huge amount of records in the backend, so if you need to restart or reload often, might not worth it. On the other hand, you can add/remove by
item from hash table.<br>
<br>
