[Bug 481299] New: Yast Scanner Model and Driver Devours system resources at the expense of basic O/S
https://bugzilla.novell.com/show_bug.cgi?id=481299 Summary: Yast Scanner Model and Driver Devours system resources at the expense of basic O/S Classification: openSUSE Product: openSUSE 11.0 Version: Final Platform: x86-64 OS/Version: openSUSE 11.0 Status: NEW Severity: Normal Priority: P5 - None Component: YaST2 AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: alpha096@virginbroadband.com.au QAContact: jsrain@novell.com Found By: --- User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-GB; rv:1.9.0.6) Gecko/2009012700 SUSE/3.0.6-0.1 Firefox/3.0.6 I attached a Cannon USB scanner and went to Yast>Hardware>Scanner to configure it. This Yast Model consumes vast system resources and 10% mac CPU and as Much Physical RAM as it want to constrict the driver database. Auto detection took over 2 Minutes. Once the scanner Model is auto found I edited the selection to ensure the most appropriate selection - again System Resources were swallowed up like nothing on earth. This process took over 2 Minutes Once the List of Drivers were displayed I entered a search string which again started to devour more resources again taking over two minutes. Once Again selecting the "Show Complete List" took over 3 mins and consumed more resources. My PC is a Processor (CPU): AMD Athlon(tm) 64 X2 Dual Core Processor 4600+ Speed: 2,410.96 MHz Cores: 2 with Total memory (RAM): 1.7 GB Free memory: 696.9 MB (+ 412.2 MB Caches) Free swap: 10.0 GB The Free memory amount started at 980MB and this small yast program has reduced it to a current 696.9MB and is dropping all the time Reproducible: Always Steps to Reproduce: 1.Auto detect any USB Scanner and monitor sysinfo in Konqueror as above 2. 3. Actual Results: Totally unacceptable and unrestrained use of system resources and inordinate wait times - we must and can do much better with this module! Expected Results: I am sure we dont need 1 Yast module to be 1 able to access seemingly unrestricted resources and I am sure we can either index the data base better to cut down searches and possibly consider using a bubble sort rather than straight index sort. The PC has been processing "Show complete List for over 5 minutes now and available RAM has dropped to 580MB and going down -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

/var/lib/YaST2/scanner_database.ycp 2009-03-26 09:34:40 <1> linux-ncbv(6392) [YCP] Scanner.ycp:327 Executing bash commandline: /usr/lib/YaST2/bin/determine_active_scanners YCP /var/lib/YaST2/active_scanners.ycp
This takes 21 seconds; whole run of yast2-scanner takes c.a. 30 seconds, at most 50 seconds (there is a 20-second gap in the log before another module is started); this is tne only run of the scanner module which I found in the logs Would it be possible to get logs (ideally with Y2DEBUG=1 environment variable) showing that any operation really takes at least minutes? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
