Hi,
This page: http://developer.yahoo.com/performance/rules.html#flush
recommends using a flush() call just after the </head> tag. However,
does this even have an effect when using ob_gzhandler() ?
Cheers.

I use Dreamweaver as my editor, mainly because I'm familiar with it, although I
only use
about 1% of its capabilities. However it generally handles long files well.
The other day
I downloaded the two shortest of Brian Dunning's sets of test data *. I opened
the
shortest in Dreamweaver, had a quick look at it, and realised I would have to
replace the
quote, comma, quote separators with semicolons, as part of converting the files
to my
format.
So I thought I would do that while I was working out what else I had to do. I
entered the
old separator and the replacement in the 'Find and replace' window, then hit
'Replace
all', expecting the job be done in a few seconds. First I thought nothing was
happening,
but then I realised it was trudging through the file, as if it was wading
through waist
high molasses.
So I closed the results window, and opened another file, but a few seconds
later focus
switched back to the original file. I tried a couple of times more, but each
time it
returned to the original window. I watched in morbid fascination for a bit,
then decided I
would let it go, just to see how long it took.
The file contained 500 lines, and was about 80 K. It was taking five seconds to
process
each line, and eventually finished in about 40 minutes.
The problem appeared to be the results processing. I have only looked at the
results list
about twice, out of idle curiosity, but never saw any thing that I thought
could be
remotely useful. I would like to be able to turn results logging off
altogether, as it
wastes real estate (and time!), but this appears to be impossible.
On this occasion the program was apparently writing a new line every time it
replaced a
separator (9 times in each line), and then when it finished processing a line
it would
erase all the intermediate result lines, and write a new one for the whole
line. At the
same time it reopened the results window if I had closed it, and return focus
to the file
being processed.
I then wrote a PHP program to read the file, split it, clean up and re-arrange
the various
elements, enter them into an array in my format, and finally save it as a file
my program
could handle.
After I had got this running on the 500 line file I used it to process the
5000 line
file. The whole process was done in the blink of an eye -- literally a fraction
of a
second.
