To facilitate testing of Eclipse under large loads, we have constructed a "big workspace". Basically it is all of the I20021127 build Eclipse projects loaded from CVS. This includes all the tests, all features, the doc (without Javadoc) and of course, all plug-ins. In total there are some 70,000 resources in about 135 projects.
The download is actually two separate files because WinZip does not support more than 64K files in one archive. Combined they are 98MB zip'd and 170MB unzippedd (you'll need more depending on your disk's block size).
Getting the workspace is straightforward, just fetch the zips and extract the files into a common directory (say c:/big). Then run
eclipse -data c:/big
