[Fedora-directory-users] RE: reducing memory footprint?

[Gerald Richter]

Hi all,

Thanks for your suggestions.

I tried it out and here is the result (everything is after startup and
without any load or work. The numbers are the virtual memory that ps shows):

- default configuration ~ 122MB

- reduce db cache from 10MB to 1 MB ~ 113MB

- reduce number of threads from 30 to 3 ~ 57MB

- disable unneeded plugins ~ 55MB

BTW This is still a factor of 5 higher than OpenLdap, which takes about 10MB

seems that FDS is good for huge databases with high load, but not for the
small ones with limited computer resources.
