A question on modelling binary response data using factors
...C5 24 76
I to compare individual rates against the overall rate, and look at
difference across pooled rate for each factor
Doing hand calculations, it is possible to calculate the individual hit
rates, the overall hit rate of the pool, and the standard errors on these
using hitrate = hits/(hits+misses) and hitrateerror =
sqrt((hits+misses)*(hits/(hits+misses))*(misses/(hits+misses)))/(hits+misses)
Again doing hand calculations, it is possible to extract the influence of
each variant of each factor, by producing a "pool" and comparing the
influence
of each varian...

Some performance questions with ZFS/NFS/DNLC at snv_48
...) two types of performance issues we''ve run into..
1. DNLC-through-ZFS doesn''t seem to listen to ncsize.
The filesystem currently has ~550k inodes and large portions of it is
frequently looked over with rsync (over nfs). mdb said ncsize was about
68k and vmstat -s said we had a hitrate of ~30%, so I set ncsize to
600k and rebooted.. Didn''t seem to change much, still seeing hitrates at
about the same and manual find(1) doesn''t seem to be that cached
(according to vmstat and dnlcsnoop.d).
When booting, the following message came up, not sure if it matters or not:...

dovecot2: authcache statistics
Hello,
setting auth_cache_size to nonzero enables caching of authentication data.
The cache hitrate may be logged by sending SIGUSR2 to dovecot/auth process.
Is it possible that dovecot logs statistics on regular intervals ?
( like http://www.postfix.org/postconf.5.html#anvil_status_update_time )

I would argue it is quite difficult to identify intelligence. I am

php-cgi frozen with sbwait when SMP enable
Hello,
I have 4 web servers with lighttpd to serve one web site with DNS load
sharing. On the 2 SMP-enable web servers, there will be many php-cgi frozen
in 'sbwait' state every day. It means the php-cgi stay in 'sbwait' state,
and never be back to 'accept' or other state. If I restart them, there will
be frozen php-cgi appear some hours later.
There is no problem on the
