I have tried both Diskeeper and PerfectDisk and I must say they both took over 24 hours to defragmentate my 130gb partition and I never really noticed much of a speed difference.

Now however I have formatted my computer and I am looking to try either Diskeeper of PerfectDisk again. So which one do you think I should go for?

Feedback would be appreciated.

P.S. This is an independant thread from the "best defrager" as I only want feedback on the above mentioned two products. So dont be giving me stick about how this question is asked at least 10 times a week.

Thanks

Martyn

same here , i prefer perfectdisk to diskeeper, you can visit thire homepages, look around the guest messages or their forums, i think that a good way to make your decision.

in my sight, perfectdisk is much better than diskeeper, i use to use both of them.

IIRC, when defragging, try not to write to be writing data to the same partition/disk that's being defragged. That could be the cause of your dramatic slowdown.

Most modern defrag programs are ultimately similar though. The first defrag takes the longest, but subsequent ones (assuming they're not too irregular) should take a fraction of the time.

A way to avoid writing to the disk would be to install the program on another partition and then defrag it?

As in now my main partition is XP and my secondary on is ME. So if I installed PerfectDisk on ME and defragged XP from there would it be considerably faster than defragging XP on XP?

I'd have to say PerfectDisk after using it and knowing someone who works at Raxco. I've managed to run questions and such by him regarding PerfectDisk vs Diskeeper and I'm satisifed that PerfectDisk does have a better defragging and smart file moving technology than Diskeeper does. Also he does get copies of Diskeeper from Raxco just for working there for which he has donated to our organization (www.savelostriver.org) to help pay our legal fees. But back to the defragging stuff... PerfectDisk for me.

Honestly, I dont know how these 2 progs defrag differently or which is better. But one thing I do know is that Diskeeper defrags a whole lot faster. Is it doing its job? I dont know. At least it is good at fooling me. I do hate the background services that DK uses though.

the poll means nothing as most people are ignorant, just look at AV programs, bloated crap like norton usually gets the highest vote.

just look at the file size, Perfectdisk 3mb vs Diskeeper 18mb, obviously there is something very wrong with DK, it must have installed a lot of useless craps into your computer, just like norton creates millions of entries in the registry and installs all sort of garbage, kaspersky does it better in less than 20mb, compare to norton >200mb.

the ranking for defrag programs:

1. perfectdisk

2. o&o

3. Vopt XP, diskeeper and others.

if you like unnecessarily big bloated programs like norton, then diskeeper is for you.

well said, tho i found diskeeper better than o&o (in sig) but I plan to retest many of the apps later on, it's ever-changing

it's very true, see post 12, many users haven't tried the other app, this can greatly affect the votes

When are you going to be adding more apps as I really like you guide?

      That reminds me. Now that i have Quest 3 I should go back and try the first one in VR. ... last time i did that I tried it in some janky VR setup which was still really good.

      An actual cosmic "Eye of Sauron" had been looking straight at us all along by Sayan Sen Image by Kovin P. Vasquez via Pexels | Not representative An international team of researchers has solved a long-standing mystery surrounding a distant blazar known as PKS 1424+240, helping explain why it produces some of the brightest high-energy gamma rays and cosmic neutrinos ever observed despite appearing to have a relatively slow-moving jet. The findings were published on June 6 in Astronomy & Astrophysics Letters. The study addresses a broader challenge in astrophysics: understanding how extreme cosmic objects accelerate particles to very high energies and produce very high-energy (VHE) photons and neutrinos. PKS 1424+240 is located billions of light-years from Earth. It has attracted attention for years because it is both a powerful source of VHE gamma rays and the brightest known neutrino-emitting blazar in the sky, according to observations by the IceCube Neutrino Observatory. It is also associated with one of the strongest peaks in IceCube's nine-year neutrino sky map A blazar is a type of active galactic nucleus powered by a supermassive black hole that pulls in surrounding matter and launches jets of plasma moving close to the speed of light. What makes blazars unique is their orientation. One of their jets points almost directly toward Earth, making them appear exceptionally bright across the electromagnetic spectrum and allowing scientists to study some of the most extreme physical processes in the Universe. The scientists exclaimed it's like the 'Eye of Sauron' in deep space. Usually, the brightest gamma-ray-emitting blazars are expected to have jets that appear to move very quickly. However, radio observations of PKS 1424+240 suggested that its jet was moving much more slowly, creating a contradiction that became part of a long-running problem known as the "Doppler factor crisis." To investigate, researchers analyzed 15 years of observations from the Very Long Baseline Array (VLBA), a network of 10 radio antennas spread across the continental United States, Hawaii and St. Croix. Using a technique called Very Long Baseline Interferometry (VLBI), astronomers combine signals from widely separated radio telescopes to create a virtual Earth-sized telescope capable of revealing extremely fine details. The team combined 42 polarization-sensitive radio images collected between 2009 and 2025, creating a much deeper and more detailed view of the jet than had previously been possible. The observations were carried out as part of MOJAVE (Monitoring Of Jets in Active galactic nuclei with VLBA Experiments), a long-running program that studies the brightness, polarization and magnetic field structures of jets produced by active galaxies. The project aims to better understand how activity near supermassive black holes is linked to high-energy radiation and neutrino emission. “When we reconstructed the image, it looked absolutely stunning,” said Yuri Kovalev, lead author of the study and Principal Investigator of the European Research Council-funded MuSES project at the Max Planck Institute for Radio Astronomy. “We have never seen anything quite like it — a near-perfect toroidal magnetic field with a jet, pointing straight at us.” The image revealed an unusual geometry. The researchers found that Earth lies almost directly in line with the jet, with a viewing angle of less than 0.6 degrees. In simple terms, astronomers are looking almost straight down the jet. This turned out to be the key to the mystery. Because the jet is aimed almost directly at Earth, a relativistic effect called Doppler boosting dramatically increases its apparent brightness. The study found that this effect boosts the emission by a factor of about 30 while also making the jet appear slower than it actually is. “This alignment causes a boost in brightness by a factor of 30 or more,” said Jack Livingston, a co-author at the Max Planck Institute for Radio Astronomy. “At the same time, the jet appears to move slowly due to projection effects — a classic optical illusion.” The nearly head-on view also gave scientists a rare look at the jet's magnetic field. Using polarized radio signals, they detected a clear toroidal, or doughnut-shaped, magnetic field component. The observations suggest the jet carries an electric current and that its magnetic field helps launch, shape and stabilize the flow of plasma. Researchers believe this magnetic structure may also play a key role in accelerating particles to energies high enough to produce both gamma rays and neutrinos. “Solving this puzzle confirms that active galactic nuclei with supermassive black holes are not only powerful accelerators of electrons, but also of protons — the origin of the observed high-energy neutrinos,” Kovalev said. The research was conducted under the MuSES (Multi-messenger Studies of Energetic Sources) project, which investigates how active galactic nuclei accelerate particles and generate different cosmic signals, including light and neutrinos. Scientists say understanding how protons are accelerated and linked to neutrino production remains one of the major unanswered questions in astrophysics. The findings help explain why some blazars can appear to have slow jets while still producing extremely bright high-energy emissions. More broadly, the study strengthens the link between relativistic jets, magnetic fields, gamma rays and high-energy neutrinos. Researchers say the results provide new clues about how some of the Universe's most powerful natural particle accelerators work and offer important insights for multimessenger astronomy, which combines different types of cosmic signals to study extreme events in space.
