wow, Quanah,<br>
<br>
that&#39;s the best answer i ever got...<div class="im"><br>
<br>
I&#39;m gong to move to 2.4.18 and try to tune up the machine... regarding<br>
more RAM ... i can get it but not tha fast.<br>
<br>
what can i expect with a total of 10 GB ?...<br>
<br>
I plan to set set_cachesize 7 0 1<br>
<br>
what is the relation between cachesize (in slapd.conf) and set_cachesize<br>
(in DB_CONFIG)?<br>
</div></blockquote>
<br>
They aren&#39;t related.  cachesize (in slapd.conf) is for the entry cache. set_cachesize is for the BDB backing cache.<div class="im"><br>

set_cachesize =&gt;how much memory i wiill cache<br>
cachesize =&gt; number of entries i will keep within the cache<br>
<br>
how much one entry take ?<br>
<br>
Lets say if i use 7 GB of cache, what cachesize should i put?<br>

Hard to say. ;)  A bit of the BDB cache will likely be swapped out.<br>

It has some zimbra specific commands in it, but it should be fairly trivial to see how it maps to your openldap install.  I&#39;d also particularly read over the bit about using a shared memory key for the BDB cache once you go beyond 8GB cachesize (which you will do after you get more RAM. ;) ).<div>
