Slow Filemaker PHP request every 30 seconds

[serzone]

I'm having some serious problems with my installation of FileMaker Server 14 and PHP. Everything seems to have installed properly and seems to be working fine except for one thing:

If I make a php api request to get a record for example from a FileMaker database that request takes forever... 10-20 seconds, the immediate subsequent requests are as fast as you'd expect them to be, they just work. Then 30 seconds later it's as if I'm making that first request again, 10-20 seconds to get that record.

Additional info:
Server is Intel Xeon E5430 8 core @ 2.66 Ghz with 24GB RAM running Windows 2008 R2 64bit
IIS 7.5
FileMaker Server 14 v3
The database/layouts/record/fields I'm using for troubleshooting this is are as bare-bones as possible (new db, 1 table, 2 fields, no calcs, no crazy layouts, no heavy traffic due to other apps).
