This commit applies eight low-risk internal optimizations identified
in the performance audit. No wire protocol changes — 100% MikroTik
compatible.
Changes:
- ecsrp5.rs: Cache WCurve in a global LazyLock, eliminating the
expensive BigUint modular square root recomputation on every
EC-SRP5 authentication. Also optimize the local hex::encode
module to use a single pre-allocated String instead of N format!
allocations.
- server.rs: Deduplicate Instant::now() calls in the TCP TX hot
loop, caching the result at the top of each iteration.
- csv_output.rs: Hold the CSV file handle open in a static
Mutex<Option<(String, File)>> instead of reopening the file on
every write_result call. Add explicit flush after each write.
- server_pro/user_db.rs: Replace hand-rolled Gregorian calendar
math (30+ lines looping from 1970) with chrono::Local::now().
Optimize hash_password() to write username:password directly
into the SHA256 hasher and hex-encode with a pre-allocated
String.
- server_pro/enforcer.rs: Replace allocating error string matching
(format!({}, e).as_str().contains(...)) with direct
QuotaError variant matching. Pass ip_str into flush_to_db()
to avoid a per-call ip.to_string().
- syslog_logger.rs: Move timestamp formatting outside the global
std::sync::Mutex to reduce lock hold time. Replace manual
calendar arithmetic with chrono::Local::now().format().
New dependency: chrono (already pulled in transitively by rusqlite).
