Is there a difference in accessing the Cache of an application when calling HttpRuntime.Cache vs. HttpContext.Current.Cache?

No they are both one and the same. However, notice that HttpContext.Current.Cache requires resolving to HttpRuntime.Cache, and hence requires that bit of more processing.  Also HttpContext.Current.Cache is not available outside ASP.NET applications.

Which is the most efficient way of getting number of rows in a table ?

select COUNT(0) from LiveDataRawString select COUNT(*) from LiveDataRawString SELECT


The last method is the most effiecient method of getting count.
Because display estimated execution plan gives 50%, 50%, 0% costs when all three are evaluated, and gives 99% and 1% when last are evaluated. rows FROM sysindexes WHERE id = OBJECT_ID('LiveDataRawString') AND indid < 2
