==== Performance considerations
{transforms-cap} perform search aggregations on the source
indices then index the results into the destination index. Therefore, a
{transform} never takes less time than the cumulated duration of the
aggregation that it performs and the indexing process.
{transforms-cap} perform search aggregations on the source indices then index
the results into the destination index. Therefore, a {transform} never takes
less time or uses less resources than the aggregation and indexing processes.
If your {transform} must process a lot of historic data, it has high resource
usage initially--particularly during the first checkpoint.
For better performance, make sure that your search aggregations and queries are
optimized and that your {transform} is processing only necessary data.
NOTE: When you use <<search-aggregations-bucket-datehistogram-aggregation>>, the
queries are not considered optimal as they run through a significant amount of
data. For this reason, {transforms} performing date histogram aggregations take
longer to run.
