TiP (Test in Progress) Measurements
TestMy.net has a high resolution download test. Unlike other speed tests TestMy.net takes measurements during the test to show you the path of your download speed over the course of the test. It conducts tests within the test. The end result is unparalleled result detail.
Information like minimum speed, average speed, maximum speed and variance from minimum to maximum speed during the test are shown along with a graph plotting the speed over time, percentage and data transferred. This extra information is logged to the database and can be a great aid in troubleshooting. Currently TiP is only available on the linear download speed test.
Great Connection
This connection quickly picked up speed, held it there and actually sped up at the end. All marks of great connection quality. Note: Sometimes little variance in speed can also point to an issue like a bottleneck.
Poor Connection
Large variance in speed can be an indication of a connection issue. TiP enables users to see this information to understand how the data flowed as the test ran.

The most simple tool: use
pdftk
(or pdftk.exe
, if you are on Windows):100 Mb File Download Test
This will be a valid PDF. Download pdftk here.
Update: if you want really large (and valid!), non-optimized PDFs, use this command:

I had problems using pdftk with the cat parameter had a better success with output.
The following command worked for me:
Using cat produced the following error:

Partly it depends on what you are trying to increase the size of.. number of pages, number of images, size of a single image. In my experience, the vast bulk (90%+) of any given 'large' PDF file will be the images.
You could try using a pro product like Adobe InDesign to quickly build a large project and export it as a PDF.
Adobe Acrobat Pro has built-in tools to optimize PDF files -- you try using the tools to 'un-optimize' your file. :)

One possibility is, if you are familiar with PDF format:
- Create some simply PDF with one page (Page should be contained within one object)
- Copy object multiply times
- Add references to the copied objects to the page catalog
- Fix xref table
You get an valid document of any size, entire file will be processed by a reader.

Have you tried using cat to combine the files?
That should result in a 20MB file.
