However, on the Pentium M rig and C2D laptop, the increased DPC latency results in random bursts of choppy audio while watching online video. On the laptop, high disk activity occasionally results in choppy UI and pointer movement.
This is exactly the problem I faced on my little ASUS x205ta laptop, which came with Windows 8.1 "Bing", but did say "plays well with Windows 10" on the box. After a variable period of time the audio was transformed into a crackling mess, and the problem seemed to be DPC latency. It only happened over HDMI - headphone out was OK - so I was convinced I could fix it, but I threw all of my nerd skills at it over the course of months and no dice.
DPC latency issues -- check your DRIVERS!
Otherwise may be related to high CPU loads due/related to System interrupts or System and compressed memory. The latter of which I really am not sure will be helping much with slow (or throttled down) CPUs, slow harddrives and low RAM.
I haven't confirmed it one way or another, but I too feel that Win10 is less merciful on harddrives, especially under heavy load or when RAM usage is already maxed up. I mean, with Win7, programs (most notorious, browsers) will just crash sooner due to insufficient memory, but in Win10 it's like it's trying to hang on longer by somewhat overmanaging memory use (and therefore abusing the poor ol' harddrive). I think I'm going to recommend a minimum of a decent 4-core, 8GB RAM and SSD today for chronic multitaskers on Win10. Or for more basic use, a fast 2-core, 4GB RAM but SSD isn't negotiable anymore.
Re:Start/desktop search
wrote:-What is up with Windows Search? It's not as quick and accurate as it was in Windows 7. Disabling Web search and Cortana helps immensely, but it's still far from consistent. For example, a search for Device Manager worked properly on 3 out of the 4 systems I tested. However, on the laptop, Search refused to find it. Very annoying. Sometimes after a reboot, Search takes a while to get back up and running.
I did have some issues (in first RTM) with Cortana disabled and going offline (somebody found out that it still tries to make several connections to certain locations! tschk...) where local search just doesn't work at all (incl. typing apps/programs names) until the system gets back online. Seems to be fixed in 1511 (10586/TH2) though.
However if you feel it's slower, take a look at 3rd party desktop search/indexer programs. Some good choices out there (no phoning home included).
