<ul></ul><p>A way to speed digitizing up was to use "Cross" instead of "Semi transparent circle" for the "Marker style" in Preferences, in my case. See if that helps and please report back.</p> QGIS Application - Bug report #1277: digitizing with snapping option works verry slowhttps://issues.qgis.org/issues/1277?journal_id=175542008-09-03T12:32:57ZGerhard Spieles
<ul></ul><p>Speed is little better, but not good for work</p> QGIS Application - Bug report #1277: digitizing with snapping option works verry slowhttps://issues.qgis.org/issues/1277?journal_id=175552008-09-04T05:43:32ZMarco Hugentoblermarco.hugentobler@sourcepole.ch
<ul></ul><p>The most effective way to speed up the snapping is to have a spatial index. Otherwise, every vertex of the whole dataset needs to be tested.</p>
<p>Do you already have an index on the dataset? If not, you may create one in the vector layer properties dialog:</p>
<p>Open vector layer properties dialog, go to tab 'general', press button named 'create spatial index'.</p>

<p>Works for me, with my data. If you can still reproduce it please open a separate ticket and attach sample data to reproduce the problem.</p>
<blockquote>
<p>(see attached pdf-file</p>

<p>FWIW, you can attach JPEGs or PNGs as well.</p> QGIS Application - Bug report #1277: digitizing with snapping option works verry slowhttps://issues.qgis.org/issues/1277?journal_id=175582008-09-05T04:05:33ZGerhard Spieles

<p>I asked you to open a separate ticket for the issue regarding spatial index. It's bad to discuss 2 separate issues in the same ticket.</p>
<p>And please upload some sample data into that new ticket (e.g. a Shapefile) to reproduce the problem with - a screendump is not enough!</p> QGIS Application - Bug report #1277: digitizing with snapping option works verry slowhttps://issues.qgis.org/issues/1277?journal_id=175602008-09-05T06:31:10ZGerhard Spieles
<ul></ul><p>Sorry, i@ll open a new ticket soon.</p> QGIS Application - Bug report #1277: digitizing with snapping option works verry slowhttps://issues.qgis.org/issues/1277?journal_id=175612008-09-17T10:24:51ZMarco Hugentoblermarco.hugentobler@sourcepole.ch
<ul><li><strong>Status</strong> changed from <i>Open</i> to <i>Closed</i></li><li><strong>Resolution</strong> set to <i>wontfix</i></li></ul><p>I'm closing this ticket as the problem is covered by the new ticket. Without a spatial index, it is not possible to have good snapping performance for large data files.</p>
