Re: [Ids-devel] IDS speed and modperl/fcgi

[happyman <hap...@co...>]

Hi all,

     I am using ids+fastcgi. The most importnat thing is fastcgi is a =
single process,
css2 happyman/public_html> ps ax |grep ids
32158 ?        S     32:04 /usr/bin/suidperl -U =
/dev/fd/3//home/happyman/public_html/ids/index.fcgi
    I made ids runing as its owner using suidperl, so the thumbnails =
too. I don't really care about thumbnail creation time.
It handles very well on my site with 2.7G photos (including =
image-cache). You can link your image-cache dir to
tmpfs (shared-memory filesystem) or install a reverse proxy to increase =
speed. (I did)]

    I think the main "lack of speed" most people are experiencing in IDS =
is
the amount of time it takes ImageMagick to create the thumbs and the =
various
image sizes.  The speed at which this operation occurs can only be =
improved
by a faster CPU and possibly a very small amount by a faster hard drive.
    FastCGI and modperl are used when a site is expecting a tremendous
amount of traffic, perhaps on the order of one dynamic page requested =
per
second or higher.  That is the point when the script and interpreter =
startup
overhead starts to load the server down.  Implementing FastCGI and/or
modperl support doesn't make any noteable speed increase to a single =
user.
It just prevents the system from buckling when you get 1,000 visitors /
20,000 page views an hour.
