In computer programming, profile-guided optimization (PGO, sometimes pronounced as pogo [1]), also known as profile-directed feedback (PDF) [2] or feedback-directed optimization (FDO), [3] is the compiler optimization technique of using prior analyses of software artifacts or behaviors ("profiling") to improve the expected runtime performance of the program.
Profiles everything running on the Linux system, including hard-to-profile programs such as interrupt handlers and the kernel itself. Sampling profiler for Linux that counts cache misses, stalls, memory fetches, etc. Open Source GPLv2 Oracle Solaris Studio Performance Analyzer: Linux, Solaris C, C++, Fortran, Java; MPI: Performance and memory ...
The news feed is the primary system through which users are exposed to content posted on the network. Using a secret method (initially known as EdgeRank), Facebook selects a handful of updates to actually show users every time they visit their feed, out of an average of 1500 updates they can potentially receive.
This allowed Facebook to monitor its competitors' performance, and motivated Facebook to acquire WhatsApp in 2014. [ 247 ] [ 248 ] [ 249 ] Media outlets classified Onavo Protect as spyware . [ 250 ] [ 251 ] [ 252 ] In August 2018, Facebook removed the app in response to pressure from Apple, who asserted that it violated their guidelines.
Meta Platforms, Inc., [9] doing business as Meta, [10] and formerly named Facebook, Inc., and TheFacebook, Inc., [11] [12] is an American multinational technology conglomerate based in Menlo Park, California. The company owns and operates Facebook, Instagram, Threads, and WhatsApp, among other products and services. [13]
A profiler can be applied to an individual method or at the scale of a module or program, to identify performance bottlenecks by making long-running code obvious. [1] A profiler can be used to understand code from a timing point of view, with the objective of optimizing it to handle various runtime conditions [ 2 ] or various loads. [ 3 ]
The difference between current performance and the theoretical performance limit is the performance improvement zone. Another way to think of performance improvement is to see it as improvement in four potential areas: input requirements; e.g. working capital, material, replacement or reorder time, and set-up requirements.
Business performance management (BPM) (also known as corporate performance management (CPM) [2] enterprise performance management (EPM), [3] [4] organizational performance management, or performance management) is a management approach which encompasses a set of processes and analytical tools to ensure that an organization's activities and output are aligned with its goals.
