i heard about it recently ,some people said it works for them so i decided to try it out.

i used cdb caching with portage 2.1_pre[something] all the time before.

so i started modyfying my configs:

first i added "-metadata-transfer" to FEATURES in make.conf
then i modified /etc/portage/modules like that
Code:
portdbapi.auxdbmodule = cache.metadata_overlay.database

#portdbapi.auxdbmodule = cache.cdb.database
#eclass_cache.dbmodule = cache.cdb.database


and after an emerge --sync i got:
Code:
sent 4683 bytes  received 3657282 bytes  31165.66 bytes/sec
total size is 134328364  speedup is 36.68

what's wrong?

your title ain't too good, and you've got it enabled it seems... ;) (portage 2.1 is ~x86 after all, we know the risks)
