10.2. Interchange slows down over time.

There are many possible reasons for this, but most have to do with memory or session database size.

• See the documentation on Interchange administration (icadmin) and learn how to expire your session database. If it is megabytes in size, accessing a key will significantly slow down the session.
• Second, if your machine is memory-poor, you will find that Interchange gets swapped to disk. Unless your system is very fast, this will greatly hurt performance. Interchange works best on a machine that rarely if ever swaps to disk.
• Third, this often has nothing to do with Interchange at all but has to do with your HTTP server. Any long-running daemon has the potential for a memory leak. Try stopping and starting your HTTP server and seeing what happens to performance.
