So i have this HP Elitebook 850 G3 company computer with Check Point End Point Security, full disc encryption and McAfee anti virus installed. I'm running Windows 7 Enterprise connected to a remote AD.
Computer specs: Intel Core i5-6300 CPU 2.5GHz, 8GB ram, 64bit OS, 256mb SSD, Intel (R) HD520 GFX, Think Pad 3.0 USB hub/display port, 2 external monitors
Symptoms: Computer is generally slow, the mouse pointer is lagging a bit, sound is studdering while browsing the web etc, programs is unresponsive. These issues seems to be related to the End Point security and McAfee since the symtoms started when thise applications where installed.
My question: I do realize the disc encryption and McAfee will affect the perfomance on my laptop but not this bad. The lack of perfomance is affecting my work. Is there any way I can determine whats causing these performance losses and how to fix them?

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. 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 0:02:36 (h:mm:ss) on all processors.
SYSTEM INFORMATION
Computer name: 5CG62501BV4082 OS version: Windows 7 Service Pack 1, 6.1, build: 7601 (x64) Hardware: HP EliteBook 850 G3, HP, 8079 CPU: GenuineIntel Intel(R) Core(TM) i5-6300U CPU @ 2.40GHz Logical processors: 4 Processor groups: 1 RAM: 7848 MB total
CPU SPEED
Reported CPU speed: 2496 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.
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): 25499,302021 Average measured interrupt to process latency (µs): 5,377540
Highest measured interrupt to DPC latency (µs): 25495,610097 Average measured interrupt to DPC latency (µs): 1,177557
REPORTED ISRs
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.
Highest ISR routine execution time (µs): 66,482372 Driver with highest ISR routine execution time: hal.dll - Hardware Abstraction Layer DLL, Microsoft Corporation
Highest reported total ISR routine time (%): 0,039108 Driver with highest ISR total time: hal.dll - Hardware Abstraction Layer DLL, Microsoft Corporation
Total time spent in ISRs (%) 0,040049
ISR count (execution time <250 µs): 152064 ISR count (execution time 250-500 µs): 0 ISR count (execution time 500-999 µs): 0 ISR count (execution time 1000-1999 µs): 0 ISR count (execution time 2000-3999 µs): 0 ISR count (execution time >=4000 µs): 0
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.
Highest DPC routine execution time (µs): 26393,0 Driver with highest DPC routine execution time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation
Highest reported total DPC routine time (%): 0,530519 Driver with highest DPC total execution time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation
Total time spent in DPCs (%) 0,905349
DPC count (execution time <250 µs): 876512 DPC count (execution time 250-500 µs): 0 DPC count (execution time 500-999 µs): 1856 DPC count (execution time 1000-1999 µs): 623 DPC count (execution time 2000-3999 µs): 185 DPC count (execution time >=4000 µs): 0
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: firefox.exe
Total number of hard pagefaults 394 Hard pagefault count of hardest hit process: 190 Highest hard pagefault resolution time (µs): 12317,100160 Total time spent in hard pagefaults (%): 0,028331 Number of processes hit: 18

1is there a question ? – conquistador – 2017-02-16T10:59:36.607
Oh darn, realized i didnt actually asked a specific question haha. Yes my question is: concidering the specs on the computer, i feel it should run much smoother than it does. I do realize the disc encryption and mcafee might slow it down but as it is not its very bad!
Is there any way to determine what's causing these performance issues and how to "fix" it? – user3120374 – 2017-02-16T11:26:32.557
1the disk encryption causes slow page faults (reading data from disk). so try without disk encryption and if this also doesn't fix it, try it also without mcafee – magicandre1981 – 2017-02-16T17:22:30.157
