Hi! Thank you for continuing development of Geeqie. I am a long time GQview user. I use some other viewers as well.
Here are some speed comparisons which might be interesting. I've done them on an old P3-600 single CPU computer, which demonstrates the differences (absolute values are not significant in this comparison) quite well. All programs were compiled with -O2, kernel is 2.6.27.7, the versions are: * Geeqie 1.0beta2 * GQview 2.1.5 * KuickShow 0.8.13 * Xzgv 0.8 The resulting times in seconds were measured with the time command, user cpu time only, numbers are averages of 5 tries, plus one pre-try not measured so that everything is always in memory cache. With the exception of Xzgv, all are very slow to load a folder full of files, and Geeqie is the slowest by far. This is what hurts the most the current user experience with Geeqie in my opinion, because if you move or add files the wait times accumulate. Geeqie is the best at zooming an image, and the worst at displaying progressive JPEGs. Displaying non-zoomed normal (baseline) JPEGs is ok, but GQview is quicker, which should not be! ;-) Xzgv is the fastest overall. This sure has to do with its reduced set of features, but its display code might be interesting. Regards, Arnd PS: Results 1) Program startup === 1.1) Empty folder ---- geeqie: 1,20 gqview: 0,41 kuickshow: 1,14 xzgv: 0,12 1.2) Folder with 5100 images (1st image very small) ---- geeqie: 10,7 gqview: 7,1 kuickshow: 6,0 xzgv: 0,2 2) Image loading ===(only 1 image in folder, without startup time) 2.1) Baseline JPEG, 6000x4690, no zoom ---- geeqie: 10,1 gqview: 9,9 kuickshow: 11,5 xzgv: 9,2 2.2) Baseline JPEG, 6000x4690, zoom to window ---- geeqie: 12,8 gqview: 22,6 kuickshow: 15,4 2.3) Progressive JPEG, 1638x2000, no zoom ---- geeqie: 8,0 gqview: 6,4 kuickshow: 0,7 xzgv: 0,6 2.3) Progressive JPEG, 1638x2000, zoom to window ---- geeqie: 10,0 gqview: 9,5 kuickshow: 8,8 ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
