Analyze Trace files

The human readable trace file might be too much to manually process.

The following will print only lines where the time took longer than 0.1 seconds

trace.pl
#!/usr/bin/perl
 
$last = 0;
while(<>){
    @fields = split(/\s+/);
    $diff = $fields[1] - $last;
    $last = $fields[1];
 
    if($diff > 0.1){ # adjust number here
        print "+$diff\t";
        print $_;
    }
}

To quickly enumerate the number of function calls:

cat trace.xt |awk -e '{print $4}' |sort |uniq -c |sort -n
