Hi,
I just did some testing with a DataGridView which had 20 rows and 4 columns. All I did is realtime updating 1-3 of the rows in the datagridview at a rate of max. 4 updates per second.
However, this spiked my CPU usage up to 60% but I've seen software that uses only about 2-6% CPU power to do similar processing.
What is the reason for this bad performance and most importantly .. what can I do about it? |
