warp mode and clock

[Marcuz]

i'm not sure if warp mode is intended to work this way, maybe it is, if it speeds up cycles in CPU? boh...
however, i've noticed that it speeds up Amiga clock while enabled. curiously it interacts also with JIT, so that if warp mode gets enabled while JIT are on, and you then desable warp, the clock timing almost don't slows until JIT gets desabled too.

as a side question, does warp affect any way the write timing on HDF?

I am not sure what do you mean.. Warp mode speedup EVERYTHING (how else it could keep internal timing in sync?)

JIT is the usual special case, strange things can happen..

Another confusing question.. (of course it does but I think you must have asked something else..) Please be more specific...

well i don't know, i thought that for making it work, inside winuae there were little magic squirrels!

seriously, i meant that i tryed to use warp to speed up the copy of a couple of hundreds files from a mounted hdir to my main HDF.

i cannot produce hard numbers, i just thought that, while i had the directories opened in diropus, and so i could see that all the files to be copied were more or less the same lenght, either with or without Warp enabled, the writing speed was alike.

more conspicuous it seemed that with warp mode on the copying experienced little stops, like it was waiting for something to catch on. but this is just a feeling.

the writing speed is really low in any case, but that, i guess it is because it tries to be alike the original speed on amiga?

I find that when copying large amounts of small files in WinUAE, Warp mode can be slower.

Don't know why, I just got on with it

I think I understood the question now

Warp-mode in fastest possible modes increase the speed of custom chipset emulation only (frame rate limit disabled) but it does not increase cpu speed (because it is already fastest possible..)

Harddisk operations probably gets slower because of increased host CPU load. (they won't get faster because cpu emulation is already fastest possible, note that disk emulation gets faster because disk hardware is synced to custom chipset and cias)

Only in A500-mode chipset and cpu emulation stays in sync (running Amiga program don't see any difference)

I figured it was something that happened for a reason, rather than a bug

[Marcuz]

yep, me too, but i was curious
thanks for the explanation Toni

Mod thread lol.

Maybe this should be moved to the mods' forum then
