Indexed View vs. Table
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I had a long running query (relative to the data) that was hitting an indexed view. I thought an indexed view was physically stored data? I dumped everything into a table and ran the same query against the table and found that it executed almost 3x as fast. I was under the impression, which apparently was wrong, that an indexed view would act the same as a physical table in terms of performance. Just looking for an explanation.

SQL Server Management Studio version doesn't usually matter. runselect @@versionon your system and see if it matches what you posted, which would be sql server 2016
