OK, these all should work fine, for purposes of the problems you're
reporting.  You should be aware that those versions of Apache and PHP have
security problems; you should upgrade to 1.3.14, and the Horde version of
3.0.17, as soon as you can.

Is it the browser timing out, or are you getting "Fatal error: Maximum
execution time exceeded" errors?  The latter is a PHP error; you can look
at upping the memory_limit and max_execution_time parameters in the
php3.ini file.

Also, Chuck has suggested in the past that for very large text files, PHP
4 has a built-in word-wrapping function that really helps performance, so
upgrading to 4 may also solve your problem.

What kind of server are you using?  (It isn't something really slow or
memory-limited is it?)
