Herolab a heavy app? You run it off WD blue drives or something?
Herolab is fast even on my Surface 3 Pro with the dual core i5 Haswel and 4GB ram. Now all my systems run SSDs so compiles and loads are very fast, but even on my crap lappy at work its fast once it compiles and loads (but that compile is dreadful, we have cheap slow drives here).
Herolab though is a single threaded app so thread to clock on core0 is all that matters, the rest is window dressing. At game nights I run it on my S3Pro with out any speed issues, other than the normal win10 hicup I have now encountered since build 74, but thats a preview issue (nothing like beta), however on my desktop or game lappy its never even blinked, even after the import of data files its ony a few seconds to compile, but again it is run from SSDs on both lappy and desktop.
My desktop is an old i7 sandy, OC'd to 4.4GHz though, but my Lappy is a i7 Ivy which clocks up to 3.4GHz I think when running single threaded apps, and 2.7GHz normally. Both run HL fast enough I am not sure I can tell the difference. Both are Win8.1 with 16GB ram, but I do not notice much slower on my Surface with 4GB.
