db stick in RAM ?

[Frank Bonnet <f.bonnet@esiee.fr>]

Hello

I'm thinking to put db files in RAM instead of hard disk
for performance reasons.

FreeBSD ( and Linux thought ) provide some utility to build
RAMDISK ( md )

I did some tests in rebuilding db files with the slapcat/slapadd
commands

with RAMDISK

ldap3# time slapadd -l test.ldif
/usr/local/etc/openldap/slapd.conf: line 110: rootdn is always granted 
unlimited privileges.
#################### 100.00% eta   none elapsed             20s spd 
633.9 k/s

WITH HARDDISK

ldap3# time slapadd -l test.ldif
/usr/local/etc/openldap/slapd.conf: line 110: rootdn is always granted 
unlimited privileges.
#################### 100.00% eta   none elapsed          04m22s spd  
48.4 k/s

Does anyone runs production servers with ramdisk ?

I know it is risky but running rsyncd between ramdisk and a hardisk 
depot would be safe huh ?

Thanks for any advices
