Downloading and displaying a pdf (Acrobat 6.0 installed) is 2 to 5 times as slow
as with IE. Very noticable as I am using a dial up connection.

I doubt the speed hit is related to downloading the data. It is probably a
rendering issue to do with the plugin.

What happens on mozilla? I don't think this is likely to be a firebird bug.

Happens here too (but only sometimes) with allmost every Firebird version so far
on Win XP and Acrobat Reader 6

I've noticed that Firebird uses 99% CPU and so the Acrobat Plugin cant load as
fast as on other Browsers.
it often helps to set Firebirds Priority a little bit lower, so the PDf Plugin
can load

Tested on 20040102 Firebird/0.7+ on WinXP.

I loaded various PDFs in Firebird and IE and found no significant difference in
load times (starting each time with Acrobat completely closed).  

The CPU spike mentioned in comment 2 occurs with IE as well (see also bug 215323).

From this I must say that loading PDFs WFM.

The Acrobat plugin does load PDFs slowly in Mozilla Firebird, but that's not a
browser problem.  -->INVALID

On a side note, tho, see this MozillaZine thread for a suggestion on how to
speed it up:
