Re: [389-users] Performance differences between 1.1.2 and 1.2.6/1.2.7

Ok, I did install a directory instance with
and loaded the exact same database. Here are the results:
I got 5630 searches/sec for the 22.214.171.124 directory instance (nsslapd-subtree-rename-switch: on)
I got 6150 searches/sec for the 126.96.36.199 directory instance (nsslapd-subtree-rename-switch: off)
I got 6890 searches/sec for the 1.1.2 directory instance.
The subtree-rename feature does have an impact on the search-performance, however 188.8.131.52 is appoxiamately 10 % slower than 1.1.2

If you see the competitive result, the cause should be entryrdn.Could be the entryrdn (subtree rename) support. Not sure. You could try disabling that.
If you are disabling entryrdn, you have to do export the DB to an ldif file, disable entryrdn, then import the ldif file back. (Sorry, there is no backward tool.)
