Talk:Accelerometers

I performed simple timing measurements for using the repeated fopen compated to using rewind on the sysfs file (as sysfs files must be seeked to start or reopened to get new information) and they are as follows:

1000 reads of values, parsing with scanf and writing to a file using repeated opening and closing of said file. real	0m 1.74s user	0m 0.09s sys	0m 0.57s

1000 reads, parsing and writing by using rewind. real	0m 1.19s user	0m 0.02s sys	0m 0.10s

This indicates that processor usage on applications with high fps and accelerometer usage could be lowered by using rewind instead of repeated fopen. Should this method of accessing the file be mentioned on the article?
