Hi all, When I do a simple string search with Yum (ex. yum search *hwinfo*) my laptop suffers high slowness. If I open another shell-tab and execute top command, it shows me an extensive use of hardware resources from Yum (20-25% RAM and 70-85% CPU). If in the same time I'm using Firefox browser the performance goes down too much and even it seems the box it's freezed. The box become totally useless during few minutes (until yum command has finished or I've killed it) More info about my old and loved laptop: * Hardware* Acer TravelMate 240 256RAM Celeron 2,5 Ghz *Software* CentOS 4.4 Final (totally updated at current day) Desktop default instalation (which means GNOME environment) ?Is this behaviour "normal"? ?What about this extensive hardware use from Yum? I supose my laptop is an old-fashioned hardware but this behaviour did not happen when I installed Ubuntu (and I did use apt to manage sofware) in same machine in recent past.

If so, yes, it is quite resource intensive, especially when you have some large repositories enabled. There is a C metadata parser that is available from the yum site, that is much faster and lighter. But it requires yum 2.6.2.> I supose my laptop is an old-fashioned hardware but this behaviour did > not happen when I installed Ubuntu (and I did use apt to manage sofware) > in same machine in recent past.APT is available from the Extras repository, and may be faster on old hardware. With kind regards, Daniel de Kok

You should see what it does to my old Pentium MMX laptop :-( -------------- next part -------------- A non-text attachment was scrubbed...
