This document summarizes a presentation about .NET performance challenges and monitoring tips. It discusses common .NET performance bottlenecks such as synchronization and locking, excessive logging, code dependencies, and database issues. It then provides tips for using AppDynamics monitoring including naming business transactions, configuring tier management, tuning snapshots, and setting thresholds. Finally, it introduces AppDynamics' unified monitoring platform that provides a single view of transactions across applications, databases, and infrastructure.

- 4. TOP .NET PERFORMANCE CHALLANGES Common Performance Bottlenecks in .NET
- 5. Synchronization and Locking • Problem: – Contention for the same resource in a heavily multi threaded environments • Solution: – Closely examine the code you are synchronizing to determine if another option is viable – Limit the scope of your synchronized block Copyright © 2015 AppDynamics. All rights reserved. 5
- 6. Excessive and Unnecessary Logging • Problem: – Duplicate exception logs across several tiers – Excessive logging of debug/info log levels • Solution: – Reduce logging to Fatal/Error/Warning in production environments – Log exceptions in the final tier Copyright © 2015 AppDynamics. All rights reserved. 6
- 7. Code Dependencies • Problem: – Reliability of external libraries – Performance of external libraries • Solution: – Is the library truly well written and well tested? – Are you using the library in the same manner as the large number of companies that are using it? – Are you using it correctly?

- 8. Underlying Database Issues • Problem: – Business logic in the Database layer vs. the application layer – Time spent on inefficient queries and data models • Solution – Improve SQL queries – Improve Data Model – Optimize business logic between the data and application layer Copyright © 2015 AppDynamics.

- 9. Underlying Infrastructure Issues • Problem: – Complex architecture that can influence performance • Solution: – Better visibility and understanding Copyright © 2015 AppDynamics. All rights reserved. 9

- 11. Business Transaction Optimization Copyright © 2015 AppDynamics. All rights reserved. 11 • Name and identify business transactions to match your business functions • Exclude business transactions that don’t add value to visibility • Configurable on query parameters, URI paths and payloads
- 12. • Detects calls across different components • Identifies HTTP, ADO.NET, MSMQ OOTB • Customizable for other exit calls Tier Management Copyright © 2015 AppDynamics. All rights reserved. 12
- 13. Snapshot Tuning Copyright © 2015 AppDynamics. All rights reserved. 13 • Visibility into code across tiers • Configurable snapshot collection policy • Displays exit calls
- 14. Machine Snapshots Copyright © 2015 AppDynamics. All rights reserved. 14 • Snapshot of machine state – CPU/Memory of running processes – IIS Application Pools – Transaction snapshots in that window • Collected: – Every ten minutes – Every six occurrences of: • CPU and memory at 80% or higher • IIS application pool queue item older than 100 milliseconds • Configurable for more frequent snapshots
- 15. Threshold Tuning Copyright © 2015 AppDynamics. All rights reserved. 15 • Thresholds control when alerts are raised and when snapshots are triggered • Three types of thresholds: – Static SLA – Standard Deviation – Percentage

Editor's Notes
- #17: Recent research from EMA says that 65 percent of enterprises employ 10 or more individual monitoring tools to keep tabs on the health of their applications and associated infrastructure. With so many tools, how do you know where to look first? How do you connect the dots to know which issues are impacting application performance, and which are not? So how do you know if it’s that minor degradation in database performance that’s slowing down your checkout process and spiking user abandonment? Or is it a server hiccup? Or a slow SQL query? This results into longer time to isolate the application problems and resolve them. The EMA research also found that 33% of application issues are reported by end-users. That means that one out of three times, monitoring solutions fail to meet their goal to identify and resolve the IT problems before impacting the customers. One of key reasons for this is delay on isolating the IT problems due to the lack of context. This might also be the reason why it takes 77 percent of enterprises more than five people-hours to fix the average performance issue, according to the same EMA study.
