  • 1.  IHS adding delay to response times

    Posted 03/21/17 03:56 PM

    We are encountering a strange issue where IHS is  adding additional time to response times. We have a JVM running on WAS 8.5.5 which is frontend by IHS 8.5.5. 

    We tested this using two scenarios, one bypassing IHS and one through IHS, When we do a webrequest through IHS, we see an increase in the response times by around 6 seconds. IHS in our case is just acting as a forwarder an do not host any content or serve. It is just passing the request to the JVM.

    We were able to see the increase in response times using an APM tool, but it would not tell us where the delay is coming from. Also this  is just  a test environment, so there is no load to keep the threads waiting or other contentions.

    Can someone help me with how I can troubleshoot this ?

    Thanks in Advance

    Hi,

     

    I would start with plugin. Turn on 'debug' in the plugin-cfg.xml, clear the http_plugin.log, make the request and post the results here. We might be able to assist.
