 Posted: Wed May 24, 2006 4:46 pm Post subject: metadata-overlay caching - how to enable it? |
 |
|
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?
