I am using konsole&#8217;s &#8220;Transparent, Dark Background&#8221; scheme, so I wanted to see if that slows me down by any considerable time compared to the plain setup.<\/p>\n<p><!--more--><\/p>\n<p>The results for <code>time ls -lar \/dev<\/code>:<\/p>\n<ul>\n<li><strong>xterm (black on white)<\/strong>: real: 0m0.141s, user: 0m0.023s, sys: 0m0.018s<\/li>\n<li><strong>konsole (black on white)<\/strong>: real: 0m0.098s, user: 0m0.028s, sys: 0m0.015s<\/li>\n<li><strong>konsole (transparent, dark background)<\/strong>: real: 0m0.103s, user: 0m0.020s, sys: 0m0.024s<\/li>\n<\/ul>\n<p>The results for <code>time cat \/usr\/share\/dict\/words<\/code>:<\/p>\n<ul>\n<li><strong>xterm (black on white)<\/strong>: real: 0m35.306s, user: 0m0.019s, sys: 0m0.512s<\/li>\n<li><strong>konsole (black on white)<\/strong>: real: 0m24.455s, user: 0m0.011s, sys: 0m0.512s<\/li>\n<li><strong>konsole (transparent, dark background)<\/strong>: real: 0m25.232s, user: 0m0.009s, sys: 0m0.547s<\/li>\n<\/ul>\n<p>I ran the commands a few times in all the terminals and the relation stayed the same, but the number fluctuated a bit, as usual.<\/p>\n<p>Conclusions:<\/p>\n<ol>\n<li>While transparency slows down konsole a bit, the change is minor and can be ignored.<\/li>\n<li>konsole is in fact significantly faster than xterm.
