[Bug 547658] New: Web browsers are taking too much time to load pages, (DNS or /usr/sbin/nscd problem)
http://bugzilla.novell.com/show_bug.cgi?id=547658 Summary: Web browsers are taking too much time to load pages, (DNS or /usr/sbin/nscd problem) Classification: openSUSE Product: openSUSE 11.2 Version: RC 1 Platform: i586 OS/Version: openSUSE 11.2 Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: EagleScreen@gmail.com QAContact: qa@suse.de Found By: --- Created an attachment (id=322897) --> (http://bugzilla.novell.com/attachment.cgi?id=322897) Time measures for OpenSuse and Kubuntu loading a web page. User-Agent: Mozilla/5.0 (X11; U; Linux; es-ES) AppleWebKit/527+ (KHTML, like Gecko, Safari/419.3) Arora/0.10.1 I saw that web browsers: Firefox, Arora and Rekonq was taking too much time to load web pages. I am talking about these averanges to load www.youtube.com in OpenSuse 11.2 RC1: 21.23 seconds for Firefox. 47.87 seconds for Arora. 31.30 seconds for Rekonq. While I saw that in Kubuntu 9.10 beta, for the same machine these were the averange measures to load www.youtube.com: 1.95 seconds for Firefox. 4.23 seconds for Arora. 4.24 seconds for Rekonq. It is evident that there is a speed problem in OpenSuse 11.2 RC1. I was investigating and I discovered that adding this line: "options single-request" to /etc/resolv.conf fixed the problem, after it OpenSuse is as fast as Kubuntu loading web pages, therefor, I deduce there is a DNS problem, /usr/sbin/nscd may not be doing its work propertly. My Internet conection is a cable-modem to ethernet port, by DHCP, DNS servers are obtained also by DHCP. Reproducible: Always Steps to Reproduce: 1. Install OpenSuse 11.2 RC1 2. Open a Web browser 3. See that it is very slow loading web pages. Actual Results: Web Browsing is very slow, unless I add "options single-request" line to /etc/resolv.conf". Expected Results: Web browsing should be faster by default, adding "options single-request" to /etc/resolv.conf shouldn't be necessary, I think /usr/sbin/nscd should work on this. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

(He said on IRC that nscd is running: "nobody 1287 0.0 0.0 1800 428 ?
