THPDFParallelRenderPipelineInfo

Reports work distribution, bounded output state, and timing for one parallel loaded-page render call

Fields

• PageCount is the number of requested input pages
• RequestedWorkerCount is the normalised caller request after processor, page-count and hard-limit clamping
• WorkerCount is the effective number of workers after memory-budget adaptation
• CompletedPageCount counts bitmaps completed successfully
• DeliveredPageCount counts bitmaps delivered through an ordered streaming callback and remains zero for the array-returning API
• CompiledPageCount counts display lists compiled by this call
• CacheHitPageCount counts pages acquired from the display-list cache without compiling a candidate
• CompiledPagesAtFirstResult records how many pages had completed compilation when the first bitmap became available
• PeakConcurrentCompileStages is the highest number of workers compiling display lists at the same time
• PeakConcurrentRenderStages is the highest number of workers playing display lists at the same time
• OutputQueueDepth is the completed-bitmap limit selected for ordered streaming and remains zero for the array-returning API
• PeakQueuedPageCount is the highest number of completed bitmaps retained for ordered delivery, including the bitmap active in the callback
• BackpressureWaitCount counts worker waits caused by ordered-window or output-capacity limits
• PeakQueuedBytes is the conservative peak byte weight of completed bitmaps retained for delivery
• FirstResultMilliseconds is elapsed time from call entry to the first completed bitmap
• FirstDeliveryMilliseconds is elapsed time from call entry until the first ordered callback begins and remains zero for the array-returning API
• TotalMilliseconds is elapsed time from call entry until all workers have joined
• MemoryBudgetWorkerLimit is the concurrency cap derived from the largest page estimate and currently available scheduler budget, or zero when budget adaptation is disabled or unlimited
• PeakPageReservationBytes is the largest conservative page estimate in the request
• PeakReservedRenderBytes is the highest summed reservation weight owned by this call
• MemorySchedulerAdmissionCount counts pages admitted by the process-wide scheduler
• MemorySchedulerDelayedPageCount counts pages that waited for another reservation to be released
• MemorySchedulerWaitMilliseconds is the summed scheduler wait time across admitted pages
• Cancelled reports that an ordered callback requested a cooperative stop
