(Please do not reply as the picture should be written in the keyboard)

Answer 1

Running a web application for a mass audiance is challenging task because of the following reasons :

1. Quality of the code : Code for any web application must be that much strong to fulfill customers requirement. There may arise problems of deadlock or memory leaks due to poorely written code for the application.
2. Users responce time : If users are not giving proper responce to the application in proper timings, then unnecessarily sessions are engaged and queue of waiting requests is incresed.
3. request in a waiting queue : As explained in above point, requests in queue may lead to poor performance of the application.
4. servers responce time(slow server) : poor responce from the server also lead to poor performance of application and it can be managed by using proper load distibution over the server and correct queries to fetch the data from the database.
5. network connectivity problems
6. quality of database :

Ways to identify performance problems in a web application

1. Code review : Code is the most important part of any application. hence if we want to reduce the performance problems then checking the code of application is a priority. Perform a code revies. the issues related to coding can be :

• inefficient code
• database connectivity in the code
• queries written for a database

2. CPU utilization : Checking of memory and CPU utilization over a perticular application is needfull to find out the performace of application.

3. Database : Structured queries written to fetch data and the database parameters should be set or written correctly. If there is a poor performace of web application, then database should be checked.
