    <p><strong>Reproduction steps:</strong></p>
    <p><span>0.- Install VLC 3.0.4 x64</span></p>
    <p><span>1.- Enable TAM</span></p>
    <p>2.- Open an audio mp3 file</p>
    <p>3.- VLC takes more than 30 seconds to open and start to reproduce the mp3 file</p>
    <p>4.- If You close VLC and try again, will open fast, but with every new session, or in the same session after some time, again You may get slowdown execution VLC.</p>
    <p><span>I'm not getting this behaviour with all applications + TAM enabled, but probably it is reproducible with others. </span></p>
    <p><span>I already reported this behaviour some years ago during beta testing of previous build of Kaspersky KIS/KTS.</span></p>
    <p><span></span></p>
    <p><strong>Actual result:</strong></p>
    <p><span>VLC takes more than 30 seconds to open.</span></p>
    <p><span></span></p>
    <p><strong>Expected Result:</strong></p>
    <p><span>VLC should open in about 1 ~ 2 seconds.</span></p>

      <p>@harlan4096, Hello!  </p>
      <p></p>
      <p>Developers ask for full traces from the very beginning: </p>
      <p>1 Please, set traces to maximum level</p>
      <p>2 <span>Enable TAM (let it finish software analyze) </span></p>
      <p><span>3 Start xperf  (only after TAM is enabled)</span></p>
      <p><span>4 Open mp3 with VLC</span></p>
      <p><span>5 Please, try to reproduce "long time" mp3 start for second time  ("...every new session, or in the same session after some time...")</span></p>

                <p>Shall I use this trace.cmd file to collect xperf traces?</p>
                <blockquote>
                <p>xperf -on base+cswitch+compact_cswitch+fileio -stackwalk profile -buffersize 1024</p>

                            <p>It seems the issue is fixed, now opening a mp3 file with VLC in my system and TAM enabled (for the 1st time ina Windows session) takes about 3 or 4 seconds which is  reasonable :)</p>
