Latenz Test bei MS Surface

Schraubenverwechsler(in)
Hallo Leutz...

hat jemand ein Microsoft Surface 2 oder 3 Pro und könnte einen Test für mich machen?

Und zwar heißen die testprogramme LatencyMon und DPC Latency Checker...

mit diesem Gratistools kann man messen, ob ein Gerät für Echtzeitaudioverbeitung geeignet ist befinden sich die Programme bei der Analyse im grünen Bereich ist alles Top!
das wäre wirklich toll und mir mir dabei helfen, ob ich mir ein Surface
bei Ebay schieße oder nicht ... ach oder ihr hab vielleicht eins zu verkaufen?

Liebe Grüße und Dankeschön für die Unterstützung...

Knut

Hier ist halt kein Echtzeit-Forum und wer solche (alten) Tablets noch nutzt dürfte wohl eher die Leute zählen, die tagsüber arbeiten müssen.

DPC Latency Checker liefert auf meinem Surface Pro 2 (i5-4200U, 4GB Ram, 128GB SSD, Akkubetrieb, Win 10 1903, WLan 5GHz aktiv).
Currect Latency: 1032 µs - 1072 µs
Max: 1072 µs

Die Werte sind erwartungsgemäß Schwachsinn. Sowohl auf der Herstellerseite wie auch hier
DPC latency tests. High latency? Solved - Windows 10 Forums
steht, dass das Programm unter Win 10 (und Win 8) keine sinvollen Werte liefert.

Warum man LatencyMon installieren muss, weiss wohl nur der Programmierer. Aber heute muss ja jedes Tool irgendwelche nutzlosen Spuren hinterlassen.

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.

 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.

Top! Danke für deinen Test....Das sieht ja tatsächlich ganz gut aus! Auf wieviel speicher kann man das Teil maximal erweitern?

Also ich hätte eventuell erwähnen müssen, dass der Test so ca 10 Minuten laufen müsste um ein realistisches Abbild zu bekommen.. wärest du nochmal bereit das zu machen? *lieb guck*

dpc latency checker (das andere Programm) muss nicht installiert werden...

Schönes Wochenende wünsche ich jedenfalls schonmal...



Viele Grüße

Auf wieviel speicher kann man das Teil maximal erweitern?
Garnicht, wenn Du es nicht zerstören möchtest:
Surface Pro 3 SSD Upgrade: Surface Pro 3 SSD Upgrade I7 with 1 TB SSD!!!

MS finanziert die Geräte über unverschämte Preise für größere Modfelle (300€ Aufpreis von 256 GB auf 512 GB SSD). Da hilft nur die richtige Version zu kaufen, Surface Pro 3 mit 8/256 nicht derzeit nicht gerade selten und dafür recht günstig, wenn einen die Eigenheiten nicht stören.

Dir sollte aber klar sein, dass
(a) es sich beim Pro2 und Pro3 um recht alte Geräte handelt, die Akkulaufzeit also nur noch dann sehr gut ist, wenn es ein Gerät von Privat mit wenig Nutzung ist, dessen Akku auch recth gut behandelt wurde.
(b) das Pro2 und Pro3 einen Lüfter haben, der auch nicht unhörbar bleibt, wenn man die Rechenleistung der CPU nutzt
(c) der Akku genauso wie Ram/SSD nicht wechselbar ist.

Falls Du ein günstiges 10,8" (16:9) lüfterloses Windows-Tablet suchst, bei dem man wenigstens SSD und Akku tauschen kann, solltest Du Dir mal des Dell Venue 11 Pro 7140 ansehen. nicht aber das 7130/7139/51xx. Die 713x sind nicht lüfterlos, das 51xx hat eine lahme Atom-CPU und ist m.W.n. nicht erweiterbar.

Das 7140 (mit 4GB Ram und 128GB SSD) ist derzeit für 160-200€ zu bekommen und hat für mich als einzigen Nachteil zum Surface Pro 2 keinen integrierten Ständer.

Also ich hätte eventuell erwähnen müssen, dass der Test so ca 10 Minuten laufen müsste um ein realistisches Abbild zu bekommen..
Das ist genauso (un)realistisch wie der Test über eine Minute. Man kann an Windows soviel kaputt konfigurieren, dass diese Tests nur zeigen, wie das Gerät mit meiner zufällig gewählten Config reagiert.

Da schlägt der Screensaver zu (Log vom Dell nach 10 Min.), das Tablet aktiviert während dem Test das WLan, Windows führt irgendeinen Task im Hintergrund aus oder es sind unterschiedliche Energieprofile eingestellt.

Alles Dinge, die man bei einer echten Nutzung für solche Anwendungen halt einfach passend einstellt, ich jetzt aber mit Sicherheit weder verdrehe noch langwierig analysiere (die 904,0 µs beim SPro war ein einziger unbekannter Task, vermutlich exakt nach 10 Min oder zu einer spezielen Uhrzeit). Ich kann beide Tablets problemlos als WLan-Fernseher nutzen, mehr "Echtzeitfähigkeiten" benötige ich nicht.

dpc latency checker (das andere Programm) muss nicht installiert werden...
Es liefert aber laut den beiden angegebenen Links Schwachsinnige Ergebnisse, und das seit Win 8.

Der Witz ist eher, dass auch LatencyMon nicht installiert werden muss. Hat man die Dateien einmal extrahiert, kann man einfach den Programmordner kopieren.

CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed:                                   2295 MHz

Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.

WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

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):   904,0
Average measured interrupt to process latency (µs):   18,070669

Highest measured interrupt to DPC latency (µs):       444,20
Average measured interrupt to DPC latency (µs):       4,055490


_________________________________________________________________________________________________________
 REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

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.

Driver with highest DPC routine execution time:       ACPI.sys - ACPI-Treiber für NT, Microsoft Corporation

 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:                 svchost.exe

Total number of hard pagefaults                       940
Hard pagefault count of hardest hit process:          314
Number of processes hit:                              28

Diese Programme zum Testen der Latenz wurden schon Speziell dafür programmiert, um zu testen, ob ein System Audioechtzeitverarbeitung hinbekommt oder nicht.
Altbewährte Methode...

Jedenfalls bedanke ich mich vielmals für deine Mühe. Das hat mich ein ganzes Stück vorangebracht...

Schönes Wochenende!!
