Problème de latence

Bonjour,

J'ai mis en place un PowerEdge R250 avec Windows Server 2016 bare-metal.

Le serveur n'a pas de carte PERC, j'utilise du RAID logiciel au niveau du BIOS (S150 il me semble)

Windows est installé sur le HDD Dell (non raid)

J'ai créé un RAID 0 de 2xSamsung Pro pour les data, Windows voit ce volume que j'ai formaté en D:\

Dès l'installation, le serveur est lent et pas réactif du tout.

Sous le gestionnaire de tâche Windows, le CPU est toujours à 1% et capé à 0.2GHz.

Conf Windows avec performance élevé CPU 100%.

Avec du mal, j'ai pu installer tous les drivers manquants (DellAssistant n'a rien installé du tout).

J'ai utilisé LatencyMon et j'ai découvert la cause des lenteurs

Pouvez-vous m'aiguillez sur comment résoudre le problème ?

Merci

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. Also one or more ISR routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates. 
LatencyMon has been analyzing your system for  1:23:56  (h:mm:ss) on all processors.

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.

 

Highest measured interrupt to process latency (µs):   9332,20
Average measured interrupt to process latency (µs):   53,537761

 

Highest measured interrupt to DPC latency (µs):       9226,70
Average measured interrupt to DPC latency (µs):       16,780147

REPORTED DPCs
_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

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                       10668
Hard pagefault count of hardest hit process:          3901
Number of processes hit:                              58
