HI,

Could it be related to this?

Requests much slower than expected through IIS/AJP connector

I have a Windows Server 2016 VM with IIS and a couple of instances of Lucee 5.3.…5+92 (using Commandbox). I am using the 1.0.41 connector to connect two IIS sites to their respective commandbox/Lucee instances. What I am seeing with that setup is that going directly to the underlying commandbox instances is much faster than sending the request through IIS and the AJP connector. On average, a request directly to the underlying server is about 300ms while, on average through IIS/AJP is about 1.4 seconds. The boncode settings are minimal. ``` <Settings> <Server>localhost</Server> <Port>8009</Port> <EnableRemoteAdmin>False</EnableRemoteAdmin> <EnableHeaderDataSupport>False</EnableHeaderDataSupport> <ForceSecureSession>False</ForceSecureSession> <AllowEmptyHeaders>False</AllowEmptyHeaders> <ResolveRemoteAddrFrom>HTTP_X_FORWARDED_FOR</ResolveRemoteAddrFrom> <PacketSize>65531</PacketSize> </Settings> ``` As are the web.config settings. ``` <handlers> <add name="BonCode-Tomcat-CFC-Handler" path="*.cfc" verb="*" type="BonCodeIIS.BonCodeCallHandler" preCondition="integratedMode" /> <add name="BonCode-Tomcat-CFM-Handler" path="*.cfm" verb="*" type="BonCodeIIS.BonCodeCallHandler" preCondition="integratedMode" /> </handlers> ``` I have zero proof the the slowness is being caused by the connector or that it is being caused by IIS but it seems to be one of them (or a combination of both). Any thoughts on how to speed this up or track down the actual cause?
