Hi all,<br><br>Reading your post i am feel interested in increase my laptop performance but I don&#39;t know by where start, can someone tell me?<br><br>Thank you so much in advance and regards<br><br><div><span class="gmail_quote">

&gt; deer, list!<br>&gt;<br>&gt; I currently try to minimize the application startup-time for my<br>&gt; gentoo-laptop.<br>&gt; Even with prelink it takes about one minute to start kde and all programs in<br>&gt; autostart due to the heavy disk i/o load.
<br>&gt; In the last days I did some tests with taking a copy of my regular /usr<br>&gt; (ext3)<br>&gt; dir and storing it in a squashfs file. I then mount it as loopback device<br>&gt; on /usr. (Leaving the original copy still intact but hidden.)
<br>&gt;<br>&gt; Those are the effects I try to achieve:<br>&gt; 1. The filesystem has no fragmentation at all. Files in my regular /usr dir<br>&gt; are somewhat fragmented, but not too badly.<br>&gt; 2. It&#39;s compressed: less disk i/o and more cpu load.
<br>&gt;<br>&gt; So far the results have been promising. With the new squashfs I&#39;m down to<br>&gt; around 50 secs (-16%). But at the moment my benchmark methods are quite<br>&gt; primitve. I simply have a stopwatch nearby and meassure the time from login
<br>&gt; to when the disk is idle again. I&#39;m looking forward to some input on this.<br>&gt;<br>&gt; greets<br>&gt; Roman<br>&gt;<br>Some things that I believe help with startup time are:<br>-Os and LDFLAGS=&quot;-Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed&quot;
<br>In order to use the new --hash-styles, you need at least<br>&gt;=binutils-2.17.50.X, which is keyworded with -*<br>--<br><a href="mailto:gentoo-performance@g.o">gentoo-performance@g.o</a> mailing list<br>
