We have a fairly large interactive Objective C program that generates large save files using the Objective C Ascii Filer. The Ascii filer converts a graph of objects in dynamic memory to a representation stored in a file and allows for such files to read. The problems occur when the Ascii filer save files become larger than 1.5 Mbs. A file of this size takes about 30 minutes on a Sun 3/60 to save. On reading files of this size, the Ascii filer appears to chewup virtual memory until everything halts (we have 50 Mb of swap on our machines). Has anyone else experienced these problems? If so do you have any solutions? We are seriously considering adding a backend database in place of the Ascii Filer. Are there any databases tailored to Objective-C. We would like a persistent object store that is as transparent to use as possible. -- Ron Casselman (613) 788-5726 Systems and Computer Engineering, uunet!mitel!sce!cassel (uucp) Carleton University, cassel@sce.carleton.ca (bitnet) Ottawa, Ontario, Canada K1S 5B6.
