I am seeing a similar issue under mono/Linux. I am using Mono 2.4 verison. I
have verified it by checking mono --version. I have C# test application
which adds numbers from 0 to 999 to a listview when a button is clicked. On
Windows/.NET this operation is very fast, whereas under Mono/Linux the
listview update takes considerably long time. I can see each row being
added. Is there any way to make listview update faster?

Thanks, Jyoti
