Improving Functioning Of Coffee Application
This is a big topic to speak over every bit at that spot are many approaches which involve analyzing performance of an application starting from profiling application to finding the bottleneck.
hither I am putting around of the basic tricks for improving performance which I learned inwards my early on days inwards coffee , I volition expire on posted around approach , sense on performance improvement every bit together with when fourth dimension allows.
for immediately hither are naive's tips for making your plan run faster.
1. Use flake shift operator for multiplying together with split upwards past times two , computers are real fast amongst the bitwise operation.
2. Use StringBuffer inwards house of the string if y'all are doing lots of string manipulation it volition cut retention past times avoiding creating lots of string garbage. If y'all are using java5 hence visit StringBuilder but that is non synchronized hence beware.
3. endeavor to brand variable , shape , method concluding whenever possible that allows compiler to create lots of optimization e.g. compile fourth dimension binding hence y'all volition acquire faster output.
4. static methods are bonded compile fourth dimension spell nonstatic methods are resolved at runtime based on object type hence the static method volition locomote faster than non-static.
5. don't telephone telephone methods inwards for loop for checking status e.g. length() size() etc.
instead of doing this , role modified version
for(int i=0; i<vector.size();i++)
int size = vector.size();
for(int i=0; i<size;i++)
if y'all similar to know well-nigh FIX protocol together with its usage inwards Electronic trading or Derivatives trading e.g. Futures together with options , unusual central together with other property shape , Please run into my FIX Protocol Interview Questions, those are questions generally asked inwards Interview for an FIX developer position. It is non simply attention inwards every bit the quick reference for Interview but too opens the novel surface area of learning for newcomers.
