Slowdown of the SAN due to overusage of temporary tables
We make use of temporary tables when we develop stored procedures, but they also become very slow when there is a heavy workload. We have an ISCSI SAN running RAID 10, and our database, logs and tempdb (15 GB) are on the SAN. We think the SAN is overworked; the SQL Server shows no CPU. [...]
