ANTS Performance Profiler 8
Improve application performance: profile .NET code and database calls
How to find performance issues with ANTS Performance Profiler in five steps
Step 1: Choose the type of application you want to profile
- Choose the type of application you want to profile.
- Enter either the file path or URL for your application.
- Choose the level of detail you'd like to see, e.g. line-level timings.
- Click 'Start Profiling'
Step 2: Interact with your app as normal
- ANTS Performance Profiler automatically launches your application.
- As you interact with it, you will notice a red line appearing on the timeline. This is your application's CPU usage.
Step 3: Select a region you want to inspect
- Select the area of interest – usually one with high CPU usage – on the timeline.
- ANTS Performance Profiler will display all the methods and database queries that ran during this time, including timing data for each method and query.
- If you select a particular method, ANTS Performance Profiler will show you the line-level timings for each line of code in that method, so you can jump to the slowest line.
Step 4: Take a look at the SQL
- If you click on the orange 'SQL' icon, ANTS Performance Profiler will give you more detail on your query performance.
- You can see the text of the query, the total time to first result, average time, and hit count.
Step 5: Dig deeper into code and queries
- Clicking on the .NET icon will then take you back to the code, so you can see what method caused that query to run.
- By flicking between .NET and SQL, you can soon find out if it's the code or the database that's slowing you down.
- In this case, it was the
NearestDinnersmethod, called by the
SearchByLocationmethod that caused the slowdown rather than the SQL query.
