64er Speed Test Measurements[edit | edit source]
The following measurements were taken using the 64'er Speed Test.
See Forum64 thread 
.
All values are relative factors to a standard C64+1541:
- Format: 75 seconds
- SAVE/LOAD: 374/407 bytes/sec = about 88/96 blocks per minute
- SEQ write/read: 349/395 bytes/sec = about 82/93 blocks per minute
- Data transfer: 455 bytes/sec = about 107 blocks per minute
The 64'er Speed Test outputs "DIVISION BY ZERO" in case disk format is very fast. Use the fixed version or start using SYS2085 as a workaround.
Legend:
- ?: not measured properly (yet)
- -: not supported
- /: does not make sense on this device
- X: error

Notes[edit | edit source]
- Cartridges typically do not speed up sequential write/read (actually, this refers to CHRIN/ACPTR/CHROUT/CIOUT kernal routines used mostly by multiload games and applications) but often feature quite fast LOAD routines.
- Cartridges that use DMA (from own RAM or a parallel floppy cable) are very fast typically.
- Alternative Kernals such as JiffyDOS or Dolphin DOS speed up all operations.
- Some cartridges and kernal replacements can be combined.
- Most 1541 alternatives (1581, MMC2IEC, ...) are faster than the 1541 even with original routines.
