<p>Hi all,</p>
<p><br>
</p>
<p>I just made an interesting observation:</p>
<p><br>
</p>
<p><span>[1000 timesRepeat: [0.001 seconds wait]] timeToRun. "--> 2612"</span><br>
</p>
<p><span><br>
</span></p>
<p><span>I think the reason for this might be that Delay >> #schedule uses a critical section that is also accessed by the <span>TimerEventLoop process with the highest priority in the system, so the synchronization overhead would be the bottleneck in this
case.</span></span></p>
<p><span><span><br>
</span></span></p>
<p><span><span>Instead, if you need to produce many short delays anyway (for instance, to simulate a running process, just like me right new), you can use a busy-wait instead:</span></span></p>
<p><br>
</p>
<p></p>
<div>Duration >> busyWait</div>
<div><br>
</div>
<div><span style="white-space:pre"></span>| proceedTime |</div>
<div><span style="white-space:pre"></span>proceedTime := Time utcMicrosecondClock + self asMicroSeconds.</div>
<div><span style="white-space:pre"></span>[Time utcMicrosecondClock >= proceedTime] whileFalse</div>
