I have a user showing up in Activity Monitor Processes.
It has a lot of entries for the same session ID 250.
this same user says it is blocked by itself (250)
Wait Type: LATCH_EX
Wait Resource: ACCESS_METHODS_SCAN
Also there are for ID 250
Wait Type: CXPACKET
Wait Resource: exchangeEvent id=port1812df....

My server is really running at a crawl. Not sure if this is a side effect something else or SQL?
Thank you for any help you can offer.

1) Check which queries are running currently with http://www.sqlserver-dba.com/2012/09/sql-server-current-queries-executing-on-sql-server.html
Analyse them. What is the 250 doing ? Is it a user query or a maintenance task?
2) Is hyperthreading turned on?
