Cookies, which forces people to re-login every time.Cleaning prefetch could cause a slowdown, just like cleaning other caches like DNS and so on.Then again cleaning those caches can solve or prevent certain issues, so it really varies. If I was to use Disk Cleanup, Temporary Files, "temp" "%temp%" "prefetch" in Run and Optimize Drives (let me know if I'm forgetting anything else) in order to delete unneeded files, clean and optimize my system does using CCleaner offer any extra cleaning and optimization? Disk Cleanup cleans only Windows and even that carefully (very little), CCleaner cleans other apps, mostly browsers.You can actually add a deeper cleanup via github.com/MoscaDotTo/Winapp2 , which could cause some issues though.

(I wrote about the prefetch circuitry in detail earlier.)Memory accesses on the 8086 are relatively slow (at least four clock cycles), so we don't want to wait every time the processor needs a new instruction.The idea behind prefetching is that the processor fetches future instructions from memory while the CPU is busy with the current instruction.When the CPU is ready to execute the next instruction, hopefully the instruction is already in the prefetch queue and the CPU doesn't need to wait for memory.The 8086 appears to be the first microprocessor to implement prefetching.In more detail, the 8086 fetches instructions into its prefetch queue asynchronously from instruction execution: The "Bus Interface Unit" performs prefetches, whilethe "Execution Unit" executes instructions.Prefetched instructions are stored in the 6-byte prefetch queue.The Q bus (short for "Queue bus") provides bytes, one at a time, from the prefetch queue to the Execution Unit.7If the prefetch queue doesn't have a byte available when the Execution Unit needs one, the Execution Unitwaits until the prefetch circuitry can complete a memory access.The loaderTo decode and execute an instruction, the Execution Unit must get instruction bytes from the prefetch queue, but this is not entirely straightforward.The main problem is that the prefetch queue can be empty, blocking execution.Second, instruction decoding is relatively slow, so for maximum performance, the decoder needs a new byte before the current instructionis finished.A circuit called the "loader" solves these problems by using a small state machine (below) to efficiently

Prefetch files offer a digital snapshot of events inside your Windows operating system (OS). Because they are created when an executable program is run from a particular location for the very first time, forensic specialists can use these files to determine what was running and when.In the event of a cyber-attack, the timeline of evidence captured in Prefetch files can prove extremely useful in determining the root cause. However, unlocking their secrets is dependent on knowing the right method and having the right tools.In this example, Paula uses CQPrefetchParser.exe to analyze Prefetch to reveal the history of execution of executable programs in the OS. This tool, created by experts at CQURE, can be used to detect what kind of DLLs were loaded and also how many times a particular executable has run. Download the CQURE free tool by clicking the banner below. Using prefetch you can investigate what kind of different types of executables were running in the operating system. The CQPrefetch Parser tool has various options. It takes as a parameter a prefetch file to analyze. We can also specify only the directory that contains the prefetch files or the /out where we are able to decompress the PF file.CQPreferchParser shows all the paths that were related to that particular prefetch file, as well as modules, the different types of DLLs that were loaded when this particular executable was running. Additionally, you can see a part of the execution history, for example like how many times notepad.exe was executed and what was the last time I had it opened.CQPrefetchParser is a great tool to support us in a prefetch analysis while performing forensics, but it can itself be deleted if an attacker has administrative privileges to that computer. So, remember that you may have to use some audit tools. Prefetch Optimizer Interface.

Plugin. Guess that's correct?I have two ffmpeg encodings going simultaneously as I can't get full speed on one single encoding.Sometimes I have a total of 1X, sometimes 0.7X, and sometimes 2x but always 100% cpu, with the same scripts, even at slow speed around 0.5X, it still shows 100% cpu, nothing else is running.This is the script I´m using to test. Code: SetFilterMTMode("DEFAULT_MT_MODE", 2) SetFilterMTMode("avisource", 3) avisource("**.avi") QTGMC(Preset="slow", EdiThreads=2) Crop(2, 2, -2, -2) AddBorders(2, 2, 2, 2) Prefetch(12)I've tried different values for prefetch and edithreads.This is what seems fastest on my PC. Settings edithreads=1 makes it slower, but not much difference above 2.I guess you're not supposed to use edithreads with avs+? Any experience with this?On the qtgmc site it says only the regular MT version is supported, but that just stopped randomly all the time. Maybe 32bit memory problem? Tried different setmemorymax values, but same problem with the 32bit MT version.I'm thinking its the amount of logical cores that's the main problem here. Threadripper has 32.I've tried higher values for prefetch, but still not faster, and it then eats up all of the cpu at low speeds.Any suggestions would be greatly appreciated. 10-23-2018, 10:39 AM Site Staff | Video Join Date: Dec 2002 Posts: 14,532 Thanked 2,647 Times in 2,253 Posts I use this for simple QTGMC in Avisynth+ x64 Code: SetFilterMTMode("DEFAULT_MT_MODE", 1)AVISource("c:\file.avi")ConvertToYV16(interlaced=true)QTGMC(Preset="faster") Prefetch(6)Slow blurs too much.But I'll tweak the QTGMC based n the source quality/needs. 10-23-2018, 10:43 AM --> Free Member Join Date: Dec 2017 Location: Norway Posts: 1,685 Thanked 460 Times in 394 Posts Quote:I believe that's correct yes.

Kernel Optimizations and Prefetch with the Spike Executable Optimizer

To take place.In the second half of cycle 6, the ALU receives these control signals and computes the sum.The RNI (Run Next Instruction) and the second instruction byte from the prefetch queue cause the loader to issue Second Clock, and the micro-address forthe next machine instruction is sent to the microcode ROM.Finally, in cycle 7, the sum is written to the AX register and the flags are updated, completing the ADD instruction.Meanwhile, the next instruction is well underway with its first micro-instruction being executed.As you can see, execution of a micro-instruction is pipelined, with three full clock cycles from the arrival of an instruction until the firstmicro-instruction completes in cycle 4.Although this system is complex, in the best case it achieves the goal of running a micro-instruction each cycle, without gaps.(There are gaps in some cases, most commonly when the prefetch queue is empty.A gap will also occur if the microcode control flow doesn't allow a NXT micro-instruction to be issued.In that case, the loader can't issue First Clock until the RNI micro-instruction is issued, resulting in a delay.)ConclusionsThe 8086 uses multiple types of pipelining to increase performance. I've focused on the pipelining at the microcode level, but the 8086 uses at least four interlockingtypes of pipelining.First, microcode pipelining allows micro-instructions to complete at the rate of one per clock cycle, even though it takes multiple cycles for a micro-instruction tocomplete.Admittedly, this pipeline is not very deep compared to the pipelines in RISC processors; the 8086 designers called the overlap in the microcode ROM a "sort of mini-pipeline."10The second type of pipelining overlaps instruction decoding and execution. Instruction decoding is fairly complicated on the 8086 since there are many differentformats of instructions, usually depending on the second byte (Mod R/M).The loader coordinates this pipelining, issuing the First Clock and Second Clock signals so decoding on the next instruction can start before the previous instruction has completed.Third is the prefetch queue, which overlaps fetching instructions from memory with execution.This is accomplished by partitioning the processor into the Bus Interface Unit and the Execution Unit, with the prefetch queue in between.(I recently
