I am looking for some large public datasets, in particular:
Large sample web server logs that have been anonymized.
Datasets used for database performance benchmarking.
Any other links to large public datasets would be appreciated. I already know about Amazon's public datasets at: http://aws.amazon.com/publicdatasets/
1. Large sample web server logs that have been anonymized.
These work to start with:
There are many, many more data sets available than these (see the gamut of other answers), but this is the lowest hanging fruit that meets your original criteria. As a bonus, they have a contact link if you have specific needs they may know of.
2. Datasets used for database performance benchmarking.
This sounds like a misnomer, because you're asking for empirical data sets that describe well-defined algorithmic problems. Specifically, it sounds like you're trying to find sets of data that you can use to test and benchmark various database systems in real time, using well-defined, normalized relational data that can be used as a set of test cases for determining the most efficient solution that meets your needs.
I don't agree with this approach. Instead of finding a litany of database systems and their canned implementations, it's far better to explore the algorithmic guarantees of these systems as your first port of call. Once you've determined the algorithmic constraints that meet your needs, you can hone in on a set of canned solutions that you can benchmark on efficiency of, for example, indexing, sorting, searching, insertion, deletion, and retrieval.
Wikipedia provides a terse article on database testing concepts that you can use to determine and write test cases for benchmarking performance. For example, you might use an agnostic data access interface like JDBC and JDBC Benchmark to determine the relative timings of each operation. From here, you can hone in on a correct solution.
In short, go to the research first for determining database guarantees. Once a set of candidate solutions has been identified, you can select amongst those by testing (or otherwise determining) the constant time performance of each desired operation.
Based on Quora answers and my personal collections in my studies, an awesome-public-datasets repository was created and updated lively on GitHub:
Below is a snapshot version of this list. For a newest list, please visit Github:
This list of public data sources are collected and tidied from blogs, answers, and user responses. Most of the data sets listed below are free, however, some are not. This list comes from https://github.com/caesar0301/awesome-public-datasets.

- USDA PLANTS checklist
- Any one of the many state GIS repositories e.g. NH's GRANIT
Well for the web server logs you could always just generate them for the format you need. If you are going to test code against it etc. it will have to be tailored to the fields you want to store/parse.
For the datasets used for database performance benchmarking, you'll probably want to look at a tool that can generate data for you. Red Gate has a great one for not too much money.
Google Fusion Tables has a few.
Datasets available here as well.
Kaggle.com frequently has datamining challenges. The datasets cover a wide range of fienlds: healthcare provider data to credit history information. Perhaps something there is what you're after.
http://Quandl.com has over 10 million data sets gleaned from all over the internet. The great thing about this resource is that it gives a single way to access all of the data. The site has a free Excel plug in or there are libraries in R, Python, Ruby, etc.
I am surprised no one mentioned Google N-Grams. More on N-Grams at http://googleresearch.blogspot.com/2006/08/all-our-n-gram-are-belong-to-you.html
Perhaps some databases used as training sets for face recognition algorithms: face-rec.org
Well, this one is new and there is a challenge behind it:
