Case Study: Daewoo Securities achieves reliable 30,000‑concurrent logons and 7× faster trading performance with Altibase

Daewoo Securities - Customer Case Study

Daewoo Securities, a full-service brokerage and Korea’s market leader, was suffering major online trading outages when its DBMS could not handle the massive influx of logons at market open. The failures caused widespread disconnections, customer indemnities, reputational damage and client attrition. To resolve this, Daewoo Securities switched from its on-disk DBMS/Oracle to Altibase, deploying Altibase in in-memory mode for its trading systems.

Altibase’s in-memory database eliminated the authentication failures, stabilized connections and now handles more than 30,000 simultaneous logons while processing over 2,000 quotes per second. Altibase delivered a 6–7× performance improvement (order latency reduced from 0.014s to 0.002s), removed customer-facing outages and profit damage, and helped Daewoo Securities retain and grow its #1 market share (8.5% in 2005 to 10.0% in 2017).
