MEASURED INTERRUPT TO USER PROCESS LATENCIES

_________________________________________________________________________________________________________

The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware

request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a

DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that

event.

REPORTED HARD PAGEFAULTS

_________________________________________________________________________________________________________

Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a

memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the

process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the

audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count: msmpeng.exe

Total number of hard pagefaults 111609

Hard pagefault count of hardest hit process: 26279

Number of processes hit: 216

Oi Rafael,

Bem-vindo à Comunidade Microsoft.

Eu sou Hahn e estou aqui para ajudá-lo com sua preocupação.

O relatório do LatencyMon que você forneceu indica que o seu sistema está enfrentando problemas para lidar com tarefas de áudio em tempo real e outras tarefas sensíveis à latência. Isso pode resultar em problemas como interrupções, cliques ou cortes no áudio. O LatencyMon identificou que um ou mais rotinas DPC (Deferred Procedure Call) de um driver em seu sistema estão sendo executadas por muito tempo, o que pode causar esses problemas. No seu caso, o driver em questão é o "ACPI.sys", que é o driver relacionado ao Gerenciamento de Energia e ao Sistema de Configuração Avançada e Interface de Energia (ACPI).

Aqui estão algumas ações que você pode considerar para abordar esses problemas de latência:

1. Desabilitar o Gerenciamento de Energia da CPU: Como sugerido no relatório, desativar as configurações de redução de energia da CPU, como "Intel Speed Step" no BIOS e em "Control Panel", pode ajudar a melhorar a latência. Isso fará com que a CPU funcione em sua frequência máxima o tempo todo, reduzindo as interrupções causadas pela mudança de frequência.
2. Verificar as Atualizações do BIOS: Verifique se há atualizações de BIOS disponíveis para sua placa-mãe. Às vezes, as atualizações de BIOS podem corrigir problemas de latência e melhorar o desempenho do sistema.
3. Verificar Drivers: O relatório menciona o driver "ACPI.sys" como sendo responsável por longas rotinas DPC. Certifique-se de que todos os drivers do seu sistema estejam atualizados. Você pode fazer isso indo ao Gerenciador de Dispositivos no Painel de Controle e verificando se há atualizações disponíveis para todos os dispositivos.
4. Desativar Serviços Não Essenciais: Às vezes, serviços e aplicativos em segundo plano podem causar problemas de latência. Tente desativar temporariamente serviços não essenciais que podem estar em execução em segundo plano e verifique se a situação melhora. Como executar uma inicialização simples no Windows - Suporte da Microsoft
5. Desabilitar Processos que Causam Pagefaults: O relatório também menciona que alguns processos estão causando "hard pagefaults". Esses processos podem interromper o fluxo de áudio. Identifique os processos que causam esses pagefaults e, se possível, encerre-os ou reduza sua atividade em segundo plano.
6. Desative as configurações de economia de energia: O relatório menciona que problemas de latência podem estar relacionados às configurações de gerenciamento de energia. Você pode desativar as configurações de economia de energia no Painel de Controle do Windows e nas configurações da BIOS. Isso pode ajudar a manter o desempenho do sistema mais consistente.

Lembre-se de que a latência do sistema pode ser causada por vários fatores, e a solução exata pode variar de acordo com o seu hardware e configuração específicos. É aconselhável fazer alterações uma de cada vez e verificar se elas têm um impacto positivo na latência do sistema.

Espero ter ajudado.  Se houver algo não claro, por favor, não hesite em me avisar.
