How does partitioning improve performance in SQL Server?
Partitioning is a SQL Server feature often implemented to alleviate challenges related to manageability, maintenance tasks, or locking and blocking. Administration of large tables can become easier with partitioning, and it can improve scalability and availability.
What is partition How will you implement it?
Partitions work by dividing a table into logical partition objects. Individual partitions, each containing a unique segment of data, can then be incrementally processed either sequentially or in parallel independent of other partitions, or excluded from processing operations altogether.
Is there a partitioning feature in SQL Server?
SQL Server 2005 introduced a built-in partitioning feature to horizontally partition a table with up to 1000 partitions in SQL Server 2008, and 15000 partitions in SQL Server 2012, and the data placement is handled automatically by SQL Server. This feature is available only in the Enterprise Edition of SQL Server.

Why are there lock escalations in SQL Server?
Even after doing some great work around partitioning their tables, they are still seeing large amount of locking and lock escalations to table are happening on database. This got me curious to why this can even happen on first place.
