Re: (ITS#3851) Berkeley DB Scalability Patch
Hi Jong,
I took a look at the other effects this patch has, i.e., what happens when
you put OpenLDAP in a mixed RW situation with a version of BDB compiled
with your patches in place. The results are devastating.
Without the patch, using a 29% Write, 71% Read scenario:
630.304 operations/second
182.671 modifies/second
447.632 searches/second
With the patch, using a 29% Write, 71% Read scenario:
53.707 operations/second
15.554 modifies/second
38.153 searches/second
As you can see, the performance is more than 10 times worse with the patch
in place than without it.
This was using the OpenLDAP 2.3.4 release on a 2 CPU SunFire v210 with 2 GB
of RAM, running Solaris 8.
