Continuing to debug this issue it seems the apache::mod::default is the bulk of the compile time. I'm curious if this is a symptom of the module itself or something with 2.7.x. I moved this puppet master to the EPEL 2.6.17 RPMs and now catalogs that previously took 40-60 seconds are now down to 1-2 seconds. I noticed that during the long compile times this VM's (2 vCPU , 2GB RAM) CPU usage is at 100% from a single Ruby process that links to the PM Rack process. My other PM running same exact setup with about 50 managed hosts never has had performance issues always running 2.6.17. I'd like to move to 2.7.x for functionality of more modern modules but this PM is for an HPC and I'm already struggling to convince my predecessors that Puppetizing the HPC is not going impact performance. Is there possibly a specific version of 2.7.x or maybe even 3.0.x that may address the performance issues I'm seeing ?
