Effectively halve connection lag for queries, speeding up all queries and so interface responsiveness.
- Rework [CMMCPConnection queryString:usingEncoding:] to no longer check the connection before every query. This removes a ping from the equation and therefore effectively halves connection lag.
- Move the actual query to a thread (note this is *not* the long-desired multithreading!) to still correctly cope with http://bugs.mysql.com/bug.php?id=9678 . As soon as we upgrade the MySQL client libraries this can be removed, the code simplified, and a further processing speedup will be seen.
- When testing a ~10,000 row CSV import (=10,000 queries), the following speedups were observed:
- Local server, socket connection: 1.2x speedup
- Remove server, 30ms ping: 1.85x speedup
Slower connections will observe the biggest benefit from this commit.
