having used linker in xamarin reduce size of release build of android application, after having installed application.the application runs slower in release build compared when debugging application in debug mode. no error reported , application runs without crashing apart fact application has slowed down. creating release build without using linker not result in application slowing down. this bit confusing believe linker meant reduce application size , not affect application performance. is there explanation kind of scenario?

naive implementation: if want find p % q , subtract q p until number < q . takes p/q subtractions, , p/q comparisons. how java this, , how fast it? when java compiler sees % operator, generates 1 of typed rem bytecode instructions , e.g. irem , lrem , frem , drem , etc. actual instruction depends on type. 2 int s instruction irem . these instructions interpreted jvm, producing cpu actions obtaining remainder. most cpus these days (at least, ones capable of running java) have built-in instructions take divisor , dividend, , produce quotient , remainder pair. why % operator fast division operator / . see this q&a information on how instruction may implemented in cpu.

i'm new configuration management , deployment tools. have implement continuous delivery/continuous deployment tool 1 of interesting projects i've ever put hands on. first of all, individually, i'm comfortable aws , know ansible is, logic behind , purpose. not have same level of understanding of docker got idea. went through lot of internet resources, can't the big picture. what i've been struggling how fit together. using ansible , can manage infrastructure code; building ec2 instances, installing packages... can deploy full application pulling code, modify config files , start web server. docker is, itself, tool packages application , ensures can run wherever deploy it. my problems are: how docker (or ansible , docker) extend continuous integration process!? suppose have source code repository, team members finish working on feature , push work. jenkins detects this, runs acceptance/unit/integration test suites , if passed, declares stable build.
