It'd take a small book to answer that fully. Have a read in BOL or buy the excellent "inside sql .... " books. There is always locking by default in...

can't help with std edition as I only use enterprise. on-line rebuilds may be tricky if the index is large and a volatile table - it's possible your index may...

single column indexes rarely have the desired effect. You'll need an index to cover the three columns in the where clause as a first step.
make the first column the most...

I'm not sure it's the role that has changed so much - more people having the job title DBA who clearly are not. Whilst the breadth of SQL Server...

files usually get used in a round robin way - it used to be that if you didn't create your files all at once then the extra files were ignored....

by my maths it's 1 million rows total.
Add a where clause to your query and index the where - you'll find it goes quicker.
If the filtering is being done in...

you are not leaving enough memory for the o/s and other processes, esp with all those cores. I'd suggest you set max memory to no more than 40GB, ideally about...
