From Newsgroup: news.admin.misc
Hi,
Also responding here (besides news.software.nntp where you posted your question);
ovmethod is buffindexed. How much size should have buffer files?
INN 2.6.3
It depends on how many articles you'll store.
The "inndf -no" command will tell you how much your buffer files are filed.
Just done a few tests with buffindexed for your information:
buffindexed
-----------
% inndf -no
3277740 overview records stored
37.73% overview space used
I set up 5 buffers of 1.5GB so it means 2,83 GB of space used.
It corresponds to about 2,852,200 articles (each newsgroup an article is crossposted to counts for 1 overview record).
overview rebuild in 32 mn
expireover in 41 mn (it is the slowest method for expiry)
space on disk: fixed, and equal to the sum of the whole buffers (though
in this case, used space is only 2,83 GB)
+ 200 kb for group.index in <pathdb>
With about the same number of articles, on the same news server hardware
(a slow Intel Atom CPU N2800 1.86GHz with 2GB RAM):
tradindexed
-----------
(overview rebuild duration not noted, I'll measure it again)
expireover in 5 mn
space on disk: 2,9 GB
ovdb
----
overview rebuild in 42 mn
expireover in 6 mn
space on disk: 5,8 GB
compressed ovdb
---------------
overview rebuild in 50 mn
expireover in 5 mn
space on disk: 3,4 GB (small overview data are kept uncompressed)
ovsqlite (new storage method in INN 2.7.0)
--------
(overview rebuild duration not noted, I'll measure it again)
expireover in 10 mn
space on disk: 5,1 GB
compressed ovsqlite (new storage method in INN 2.7.0)
-------------------
(durations not noted, I'll measure them again)
space on disk: 1,6 GB (all overview data is compressed)
I hope that information will be of help.
