Hi,
I've just come across this function and I noticed that it was disabled in my mule and also disabled by default.
In the online help I found this entry about it:

Quote

HighresTimer=0|1
Option to make eMule use highres scheduling (better precision for sleeps and some timers). Currently the upload throttler takes advantage of it if enabled, which may give smoother upload performance and smoother pings while using eMule.

So to be honest, I don't really know what it does exactly and I suppose the effect is not really big.
But at least this help entry only promises advantages. Aren't there any disadvantages?
If not, shouldn't it be enabled then by default?

On some (older) OSes HighRes-Timers are a scare ressource iirc, and i do suppose they also take more system ressouces (too lazy too look it up excactly). Also they were not tested too much and there wasn'T real need to have them enabled, so thats why they are off by default.

Thanks!
Have now enabled it, but I'll probably disable it again when there's no real need for.

According to some docs, old Windows like 3.x or 9x had 55ms timer resolution; but current versions have 10-15ms timer.
High resolution timer is mostly multimedia thing. It sets 1ms resolution, but probably you would not gain much in eMule with that precision.

Ah I see, thanks.
I wonder if theoretically also USS would be able to react (very slightly) faster when enabling the option.
I think that's basically what I hoped to gain from it, but maybe I'm mixing things up here?

zz: Option to make eMule use highres scheduling (better precision for sleeps and some timers). Currently the upload throttler takes advantage of it if enabled, which may give smoother upload performance and smoother pings while using eMule. Try it at your own risk. Use this preferences.ini setting in [eMule] section to activate: HighresTimer=1

Except that, i found this and this.
