 <p>If you have a dual-core computer and a process that's taking 50%, it means it's using one core, at its maximum capability.</p> <p><br> Compiling is a complex operation ; and it doesn't surprise me that it'd use a full CPU for some time <em>(depending on the size of your project)</em>.</p> <p>Using a CPU at its maximum, a bad thing ? Well, if you have a CPU, why not just use it ;-) <br>I don't think it can damage anything, at least if that doesn't last <em>too long</em> and your CPU is properly cooled. <br>I've had my quad-core CPU run at 100% <em>(on each core)</em> for several days in a row ; I've seen absolutly no problem since <em>(the fans were working harder for that time, but it's all)</em></p> <p><br> <code>jawaw</code> is the process that corresponds to the execution of JAVA <em>(at least for some programs)</em> ; and Eclipse is developped in JAVA ; so no surprise here either.</p>
