So I support a Dynamics CRM environment where we have deployed Buffer Pool Extension to expand the buffer pool size for clean pages. This works okay in theory except that I am getting long query times with waits for "EC". Looking around this seems to relate to buffer pool extension waits. I am concerned that while expanding the available buffer pool I have introduced another bottleneck with the BPE.
Looking at the output from querying sys.dm_os_buffer_pool_extension_configuration one of the columns is file_id. To me this would indicate that BPE possibly supports multiple files, like with other database files. Does anyone have any experience with this? All documentation and examples I have seen online only show a single file. I would be interested to see if my current issues could be mitigated with adding multiple files, I just need a way to try it to be able to test.
