instead of `putc' should give nearly the same speed with bonnie (bonnie is a
benchmark program for measuring disk access).
+?? Programs compiled with glibc 2.1 can't read db files made with glibc
+ 2.0. What has changed that programs like rpm break?
+
+{AJ} The GNU C library 2.1 uses db2 instead of db1 which was used in version
+2.0. The internal formats of the actual db files are different. To convert
+the db files from db1 format to db2 format, you can use the programs
+`db_dump185' and `db_load'. Alternativly programs can be linked with db1
+using `-ldb1' instead of linking with db2 which uses `-ldb'. Linking with
+db1 might be preferable if older programs need to access the db file.
+
+db2 supports the old db1 programming interface and also a new programming
+interface. For compilation with the old API, <db_185.h> has to be included
+(and not <db.h>) and you can link with either `-ldb1' or `-ldb' for either
+of the db formats.
