<p dir="auto">I have just installed Atom 1.0.0 and it runs very slow. When I type it seems to lag every 5-10 characters for up to 2-3 seconds. The file I opened has around 3500 lines and 180 kB. I have tried using safe mode and disabling spellcheck, but it is still too slow. CPU usage peaks to 80-100% on one core as soon as I start typing.<br>
When I press enter, editor lags for 3 seconds and CPU usage spikes to maybe 80% on one core.</p>
<p dir="auto">When I open new file with only several lines, it works without the lag.</p>

<p dir="auto">I like this editor and I would like to help to diagnose this problem if someone tells me what to do.</p>
<p dir="auto">Thank You.</p>
<p dir="auto">I know this probably won't be at the top of the list, but I like to be able to print form my editor. It would give Atom a feature that Sublime or Brackets don' t have.</p>
