Analizing slow web request

There is a web service call to my web application that is taking more than a minute to be executed the first time that it is called by any user. The rest of the time takes less than 1 second.

I'm checking the purepath Tree, the API breakdown but all I see is that io is taking almost 100% of the execution time. And it is being spent at the Apache layer.

For what I've researched, this io could mean many things, so I'm running out of ideas on where to continue to find out the root cause and mitigate this.

I had to Wireshark this issue and found out that Apache was trying to reuse an LDAP connection that was closed, which timeout after 60 seconds.

My next question would be, how could I have troubleshoot that in Dynatrace?
