1. A computer-implemented method comprising: receiving a query; performing the query against a database based on an access plan, wherein the access plan indicates steps that primitives take to execute the query against a database; if benchmarking is enabled, determining whether the query already has a benchmark record in a log, wherein the benchmark record comprises first performance data; if the query already has the benchmark record in the log, determining whether second performance data associated with the performing the query indicates superior performance than the first performance data; if the second performance data associated with the performing the query indicates superior performance than the first performance data, deleting the benchmark record from the log and adding a new benchmark record to the log, wherein the new benchmark record comprises the second performance data; if the second performance data associated with the performing the query does not indicate superior performance than the first performance data, refraining from performing the deleting the benchmark record and the adding the new benchmark record; if the query does not already have the benchmark record in the log, adding the new benchmark record to the log, wherein the new benchmark record comprises the second performance data associated with the performing the query; if benchmarking is not enabled, determining whether the query runs longer than a historical average for the query; if the query runs longer than the historical average for the query, determining whether the access plan has been changed within a threshold amount of time, if the access plan has been changed within the threshold amount of time, creating a problem record in the log and increasing an amount of data saved to the problem record; if the access plan has not been changed within the threshold amount of time, creating the problem record in the log and decreasing the amount of the data saved to the problem record; if the query runs longer than the historical average for the query, determining whether the query has more than a threshold number of the problem records in the log; if the query has more than the threshold number of the problem records in the log, removing an oldest record that is associated with the query from the log; if the query does not have more than the threshold number of the problem records in the log, finding the new benchmark record in the log, comparing the new benchmark record to the problem record, and presenting a difference based on the comparing, wherein the presenting the difference based on the comparing further comprises presenting the difference between the second performance data in the new benchmark record and the data in the problem record; and if the query does not run longer than the historical average for the query, refraining from performing the determining whether the access plan has been changed within the threshold amount of time.
