| Summary | 0001574: memcpy costs performance (surprise!) | ||||
| Description | See attached graph. About 4 memcpy operations each consume 7% of the runtime of the transport service. An issue in scheduler adds another 20%. So if we fix all of these, we might get something close to 50% speed-up. | ||||
| Additional Information | Naturally, this is based on callgrind and may not be perfect, but it is a good hint... | ||||
