Multi-threaded Architecture
The Progress Version 9 database supports a multi-threaded architecture, which provides multiple paths to a database. Each self-service client can access the database and service its own requests. Each network server queues and runs requests for one or more network clients. The database broker initializes shared memory and starts a new server for each additional client or set of clients that access the database. By removing the server architecture bottleneck, multi-threaded architecture increases overall performance.
On multi-processor systems, the multi-threaded architecture allows several processes to access the database simultaneously.
