| Summary | 0003661: Slow file copy routine | ||||
| Description | Byte to byte copying is very slow. Code form src/OSspecific/POSIX/POSIX.C: // Copy character data. char ch; while (srcStream.get(ch)) { destStream.put(ch); } It can be rewritten as following: // Copy character data. destStream << srcStream.rdbuf(); // Final check. Built and checked on Linux, observed speedup up to 10x | ||||
