### Key Optimizations.
1. **Using `re.finditer()`**: This avoids creating a large list of all matches at once, as it returns an iterator which is more memory efficient, especially beneficial for large logs.
2. **Cache Frequent Attribute Access**: Access `TestStatus` attributes once and cache them, which avoids repeated attribute lookup and saves time.
3. **Direct String Slicing**: By using `line[:line.rfind(' ')]`, redundant `str.split()` operations are avoided when capturing the test case name, making line parsing slightly faster.
4. **Using `splitlines()`**: This directly iterates over lines without creating an intermediate list unlike `split('\n')`.
