Greg,All my tracks, hiking, car & cycle, are 1 second interval, & I frequently deal with multiple tracks created during the course of a days cycling or walking.
The majority of my tracks are created by a Garmin Oregon 300. When I load the tracks (generally using file / append) my laptop screen dims & everything freezes for several seconds, but always recovers. If there are several tracks with many waypoints the programme may become slower but still functions. However, I need to save the file at an early stage, and then keep saving at regular intervals as I edit the tracks, combining them, removing duplicates, and uploading them to OSM etc. If I don't regularly save the whole laptop will freeze and not recover, necessitating holding the power button for a few seconds to switch it off, and then starting again. I don't have evidence of this, but creating a track/route seems to use even more resources, so my laptop may crash more often - again frequent saving stops this.
It may be that a feature that regularly saves to disk at 2 minute intervals would alleviate this?
I hasten to add, this is not a complaint - you asked, so I'm answering. I'm a long term fan of viking & recommend it to friends. I also think that Ubuntu may be partially to blame here, as the performance of the laptops seems to have reduced over the last 2 versions of Ubuntu. It's difficult for me to say if other programmes can cause similar effects, but I do know that 'Evolution' the PIM programme is resource heavy and can slow my system causing similar problems. I think the problems partially depend on the other programmes running - Thunderbird causes less problems than Evolution, Chromium causes less problems than Firefox.
My computer is a laptop, Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz with 4GB of ram, running Ubuntu 11.10 (can also boot into windows 7, where there is a version of Viking as well, but I rarely do this & don't know if a similar problem exists). My laptop currently uses Viking 1.2.1 from the ubuntu repository, but I have used other versions loaded from git with the same results. I also make use of other laptops of various specs. & other versions of viking with similar results.
I'm quite happy to try different versions, but you may have to keep the instructions simple as I'm definitely a user as opposed to a programmer!
Thanks for your work on Viking. Regards Nick (OSM = Tallguy)On 09/01/12 00:47, Greg Troxel wrote:
It looks like someone (Rob?) has integrated my skip_same patch to only draw points if they are different from the previous - thanks! I am curious what people think of the drawing speed, especially those who routinely take 1s tracklogs when hiking. ------------------------------------------------------------------------------ Ridiculously easy VDI.
