[horde] Horde is really really slow on my machine.

[Christopher Huyler]

Thanks for responding Eric,

I was planning to use the IMP webmail for half a dozen email accounts.  It
will not get heavy traffic, at most 1 or 2 users at a time.  

Authentication is not the problem nor is the imapd service.  I also know
that MySQL runs fairly quickly.  I have a few php pages that I'm hosting now
and none of them take more than a second to load.  The test pages for Horde
and IMP also load very quickly.  I can use /horde/imp/test.php to
authenticate against the imap daemon very quickly.  However, loading every
other page in the Horde/IMP package takes a long time; the login page, the
inbox page, viewing a message, the options page, etc.  I only have IMP
installed so I can not comment on other apps.

I went through the config files looking for ways to improve performance and
the only thing I found to change was compressing the files before
transmitting them.  I know my machine takes a long time
compressing/uncompressing gzip files so I turned this feature off.
Unfortunately it didn't make a difference. 

I am inclined to think that this is a php problem but my other php pages,
although simple, do not use up so much cpu time.   This morning I tried
building php as a static module instead of a shared module, but that didn't
make a difference either.  I'm out of ideas.

This can be caused by many things.

If everything runs slow, then there is either a problem, or your 
authentication
method is slow.

Whether that is fast enough depends on what you want to do.  I sure wouldn't
try to support many users on that.  But if you just want to use it for a
small number of users it may be sufficient.

May or may not be.  You'd need to explain more what "each page" means (horde
pages, IMP pages, other horde app pages, each and every page across multiple
apps, etc).

If it is too slow depends on your needs and expectations.  There are of
course things you can do to speed it up.  But you've not given enough info
to tell if the problem is with horde, php, authentication, the machine
resources, or elsewhere.
