3store is an RDF "triple store", written in C and backed by MySQL and Berkeley DB. It is an optimisation and port of an older triple store (WebKBC). It provides access to the RDF data via RDQL or SPARQL over HTTP, on the command line or via a C API.
YARS is a data store for RDF in Java and allows for querying RDF based on a declarative query language, which offers a somewhat higher abstraction layer than the APIs of RDF toolkits such as Jena or Redland.
Jawr is a tunable packaging solution for Javascript and CSS which allows for rapid development of resources in separate module files. Developers can work with a large set of split javascript files in development mode, then Jawr bundles all together into one or several files in a configurable way.
By using a tag library, Jawr allows you to use the same, unchanged pages for development and production. Jawr also minifies and compresses the files, resulting in reduced page load times.
If web architectures, performance, or scalability are topics you would like to keep on top of (who doesn't!), then chances are, you've heard of Nginx ("engine x"). Originally developed by Igor Sysoev for rambler.ru (second largest Russian web-site), it is

Does your SQL statement have a WHERE clause? I know this sounds obvious, but don't retrieve more data than you need. However, less obvious is that even if your SELECT statement retrieves the same quantity of data without a WHERE clause, it may run faster
Why does your application run so slowly? I bet you think it's the algorithms or the fact that you are starting all your services instead of using extension points. It runs so slowly because there is a fat man sitting on it. No one can run fast when they are carrying that much dead weight.
In this introductory paper—which follows the course of the papers included in this special issue—we argue that there are currently four main apprehensions of performance. The first of those apprehensions is provided by the work of Judith Butler on performativity. We then move to a second apprehension—the rather more general notion of performance found in nonrepresentational theory, using as an example the work of Gilles Deleuze. The third apprehension of performance is that taken from work found in the discipline of performance itself. Then, the fourth apprehension concerns the reworking of academic practices as performative.
The best benchmark for a piece of graphics hardware is your own actual application, not some marketing benchmark number claimed by some hardware vendor hyping their own hardware.
If you have a busy PostgreSQL or MySQL database application, you might want to analyze the queries to see if they can be improved. Here's a little utility to help with that.
