Hi Sébastien, I'm not sure if this is related to your problems but I had issues when I was using a Windows MySQL server on a linux host when I couldn't perform a DNS lookup on the linux host. It was a custom program but it would pause for 2 seconds or so for every DB query that was run.
Simply turning off DNS lookup in the mysql config (or I guess adding proper DNS records for your arch machine on your name servers might help). http://www.linuxask.com/questions/disable-dns-hostname-lookup-in-mysql Link for more info. I also had a weird problem with firewalls on the client machine (your arch linux machine in your case) causing weird delays so have a look there if that doesn't help.

It is freshly installed, running under Arch Linux with an AudioScience card. Most of the times, when we click some buttons on some apps, Rivendell does not respond for as much as 15 seconds. You will understand that this kind of delay is unacceptable in a production environment. I have tried running ltrace against Rivendell. Results are not conclusive, as they often change, but it might give a hint on what is going on. The command I ran was: ltrace -c -C -S -o <filename> -p `pidof rdlogedit` RDLogEdit -> Action: Pressed "Voice tracker" while selecting a log. http://pastebin.com/L6s8eE4x RDLibrary -> Action: Pressed "OK" after editing a cart. 01. http://pastebin.com/dcXsCSXg 02. http://pastebin.com/0a1ipbfW 03. http://pastebin.com/ZQrY2dq6 I always ran `ltrace` only for the time it took to perform the action, then i ^C'd it as soon as the app was responsive. I suspect that it might be an issue with SQL queries taking longer than they should... Anyone having this problem? -- Sébastien Leblanc _______________________________________________ Rivendell-dev mailing list [email protected] http://lists.rivendellaudio.org/mailman/listinfo/rivendell-dev ####################### Scanned by MailMarshal ####################### #################################################################################################################################################################################################################### Attention: The information contained in this message is confidential and intended for the addressee(s) only.
