Can you please elaborate a little bit one the configuration / deployment changes introduced in the site and hosting environment before the problematic behavior started appearing? Also, can you please share with us your current server setup and any performance measuring data related to processor and memory utilization? Also, is the database located on the same server or on a dedicated data server, and what is the current connection bandwidth to that server?
If possible, please try running a copy of the website locally, and let us know if the same behavior reproduces. Thank you in advance for your kind understanding.
