Comment 5 for bug 1530609

I begin to wonder whether there are other factors that are of importance:

I put the following string into a snippet:
aabbccddeeffgghhiijjkkllmmnnooppqqrrssttuuvvwwxxyyzz

Then I type that string by using the snippet into the firefox search field at the top right.

I nearly settled at 10 ms. It worked 7 times in a row without missing one letter and the eighth time it missed one letter. So I continued raising the delay. I am now at 35 ms; it worked 5 time in a row; I heard a ventilator of the tower for a few seconds and the 6th time it missed again a letter...
