QuickFind is a cross-platform Java application for searching files in your computer. Its sole purpose is to save user time by searching the desired file almost instantly. It is designed to support all of the major computer platforms. The user can schedule caching or manually cache at any time on selected directories. Once the caching is done, all you have to do is input the name of the file you want to find.
SynCache::Cache stores cached objects in a Hash that is protected by an advanced two-level locking mechanism. Two-level locking ensures that: Multiple threads can add and fetch objects in parallel without stepping on each other’s toes; while one thread is working on a cache entry, other threads can access the rest of the cache with no waiting on the global lock, race conditions, or deadlock or livelock situations; and while one thread is performing a long and resource-intensive operation, other threads that request the same data with #fetch_or_add method will be put on hold, and as soon as the first thread completes the operation, the result will be returned to all threads. Without this feature, a steady stream of requests with less time between them than it takes to complete one request can easily bury a server under an avalanche of threads all wasting resources on the same expensive operation.
The php-dba-cache uses the database (dbm-style) abstraction layer to cache your objects, strings, integers, or arrays. Even instances of SimpleXMLElement can be put into the cache. The size of the cache file depends on the free space of your disk. The available operations are opening a given dba database, inserting a new record with a given key, getting a record with a given key, replacing the value of a record with a given key, deleting the record with a given key, and optimizing the database file.
DirectMemory is an off-heap cache implementation (a la BigMemory) to enable in-memory serialization of a large number of Java objects without affecting JVM garbage collection performance. Although serialization makes things slower, put/get operations are well in the sub-millisecond range, which is pretty acceptable in every usage scenario. DirectMemory implements cache eviction based on a simple LRU (Less Recently Used) algorithm and on item expiration.
phpCacheAdmin is a Web application for administrating and debugging Memcached. It allows you to delete or view the current contents of the server and specify the output cache time. It also has the potential to be expanded to xDebug, FileCache, radishes, and other types of caches.
The Apache Traffic Server (TS or ATS) is a modular, high-performance reverse proxy server, generally comparable to Squid. It was created by Inktomi, and distributed as a commercial product called the Inktomi Traffic Server, before Inktomi was acquired by Yahoo!. Traffic Server has been actively used inside of Yahoo for over 4 years, serving billions of requests every day. As of fall 2009, Traffic Server is an Open Source project, and in April 2010 the Apache Traffic Server was promoted to a top-level project of the ASF.
