New Post: Incredibly slow response time on large 2003 database

I'm trying to validate that I can successfully query and revoke certificates from our CA using this module. So far no luck.

Works without issue:
Get-CertificationAuthority -ComputerName <CA-FQDN>

However:
Get-CertificationAuthority -ComputerName <CA-FQDN>| Get-IssuedRequest -RequestID 5610515

Just seems to hang. I've tried multiple variants of this and thought specifying the RequestID would be the least intensive. Our cert DB is well over 50GB. Is there an upper limit to what this module can support?
