TOP .NET PERFORMANCE CHALLANGES

Common Performance Bottlenecks in .NET

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


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


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?


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


Underlying Infrastructure Issues

• Problem:– Complex architecture

that can influence

performance

• Solution:– Better visibility and

understanding


PERFORMANCE TIPS AND TRICKS

AppDynamics Monitoring

Business Transaction Optimization


• 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

• Detects calls across different

components

• Identifies HTTP, ADO.NET,

MSMQ OOTB

• Customizable for other exit calls

Tier Management


Snapshot Tuning


• Visibility into code across tiers

• Configurable snapshot

collection policy

• Displays exit calls

Machine Snapshots


• 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

Threshold Tuning


• Thresholds control when

alerts are raised and when

snapshots are triggered

• Three types of thresholds:

– Static SLA

– Standard Deviation

– Percentage
