C# vs. Objective-C vs. Solver SDK vs. Tengine Comparison Chart

Objective-C is the primary programming language you use when writing software for OS X and iOS. It’s a superset of the C programming language and provides object-oriented capabilities and a dynamic runtime. Objective-C inherits the syntax, primitive types, and flow control statements of C and adds syntax for defining classes and methods. It also adds language-level support for object graph management and object literals while providing dynamic typing and binding, deferring many responsibilities until runtime. When building apps for OS X or iOS, you’ll spend most of your time working with objects. Those objects are instances of Objective-C classes, some of which are provided for you by Cocoa or Cocoa Touch and some of which you’ll write yourself.

Tengine is a web server originated by Taobao, the largest e-commerce website in Asia. It is based on the Nginx HTTP server and has many advanced features. Tengine has proven to be very stable and efficient on some of the top 100 websites in the world, including Taobao and tmall. Tengine has been an open source project since December 2011. It is being actively developed by the Tengine team, whose core members are from Taobao, Sogou and other internet companies. Tengine is a community effort and everyone is encouraged to get involved. All features of Nginx-1.17.3 are inherited, i.e., it is compatible with Nginx. Support the connect HTTP method for forward proxy. Enhanced operations monitoring, such as asynchronous log & rollback, DNS caching, memory usage, etc. Sends unbuffered upload directly to HTTP and FastCGI backend servers, which saves disk I/Os. More load balancing methods, e.g., consistent hashing, session persistence, upstream health check, etc.
