- That 13.6 seconds was to compile *and link*, so compare it to 12.0
- seconds for Aztec C.
-
- If I use the GST feature (equivalent to precompiled headers) it
- drops to 10.7 seconds. (I know from Paul's mail that he didn't
- use the precompiled header feature of Aztec C, so I don't know
- the comparison there.) GSTs don't help much because there aren't
- many header files for the benchmark.
-
- A more interesting test for the GST feature is the following file:
-
- #include <intuition/intuition.h>
- #include <graphics/gfxbase.h>
- #include <clib/alib_protos.h>
-
- With no GST, SAS/C version 6 takes 5.3 seconds to compile this file
- (include files on hard disk, A3000/25).
-
- With the GST generated but not loaded into RAM, SAS/C version 6 takes
- 0.7 seconds to compile the same file. After the GST is loaded into
- RAM, it takes only 0.2 seconds to compile.
-
- For comparison, V5 takes 5.9 seconds to compile without precompiled
- headers and 2.2 seconds with precompiled headers.
