• 50 r/s X 8 ColdFusion servers (at peak)

• Cloud scaling

• Zero bottlenecks (literally)

• Zero slowdowns

• Active/passive data tier (SQL Server)

The Webapper Way

• How to tune/troubleshoot a ColdFusion servero Empiricalo ~ 5 different data sets (logs,

memory/thread profiling, monitoring tools)

• PASS

• How to prioritize “TNT” problems

Threads and all the rest...

• “TNT checklist” (~55-point inspection)


• Important thread pools:o ColdFusiono Tomcato Web server connector


http://weblogs.asp.net/owscott/windows-8-iis-8-concurrent-requests-limit

Recommended Thread Settings

• runtime/conf/server.xml:<Connector port="8012" protocol="AJP/1.3"

redirectPort="8445" tomcatAuthentication="false" maxThreads="525" connectionTimeout="60000" />

<Connector executor="tomcatThreadPool"... />

(Note: connectionTimeout is in milliseconds)


• workers.properties:worker.

{instance}.max_reuse_connections=500

worker.{instance}.connection_pool_size=500

worker.{instance}.connection_pool_timeout=60

(Notes: connection_pool_timeout is in seconds;

must be the same as server.xml's connectionTimeout)
