Hi,
I'm running 2.11 pl 8 on HP9000/300 with HP-UX 6.2.
I have about 60,000 articles on-line, and my history files (I
have SystemV "history.d/[0-9]" files) total up to about 4Mb.
I'm considering to use dbm in the news software, hoping this will
speed things up. I rebuilt the dbm history file, which grew to
more than 8 Mb in size. Is this normal? Since only the article ID
and the history file position are kept in the dbm file, I would
have expected it to be 50-60% of the history file size.
Johan

The dbm file is a hash table, more or less, and there is quite a bit of empty space inside it. Our history.pag is about 2.5 times the size of our history file. -- "The N in NFS stands for Not, | Henry Spencer at U of Toronto Zoology or Need, or perhaps Nightmare"| uunet!attcan!utzoo!henry henry@zoo.toronto.edu

I would suggest getting the "dbz" replacement for the DBM library package, it reduces the size of the file quite a bit, and I hear it's faster. Also, try to get the latest release of B 2.11, patch level 19. That might solve troubles as well. -- - Matthew T. Day, Sanyo/Icon International, mday@iconsys.icon.com
