The ATLAS Trigger System for LHC Run 3 and Trigger performance in 2022
An example of (left) the rate and (right) bandwidth output by the HLT streams in a typical 2022 pp run. The total HLT event rate is lower than the sum of the stream rates, because the same events may be written to multiple streams. The peak bandwidth of the TLA stream is approximately 25 MB/s, and consequently barely visible in the right hand figure. The event size per stream can vary up to a factor of 300.
