- LX 1.00 Benchmark File
- ==============================================================================
-
- See bottom of file for benchmarking setup.
-
-
- A. Test 1
-
- View all archives on DH1:
- (29 -lh5- archives, totalling 8 MB)
-
- Utility Version Time (sec) Command line
- ------- ------- ---------- ------------
- 1. LV 1.00 12.07 LV >nil: -q dh1:#?
- 2. LhA 1.38 12.07 LhA >nil: -q v dh1:#?
- 3. LX/020 1.00 12.10 LX020 >nil: -q v dh1:#?
- 4. LX 1.00 12.14 LX >nil: -q v dh1:#?
- 5. LZ 1.92 13.38 LZ >nil: -N v dh1:#?
-
- Comments: As you can see, LV, LhA, LX and LX/020 operate at almost exactly the
- same speed for the viewing operation.
-
-
- B. Test 2
-
- Test all files in archives on DH1:
- (29 -lh5- archives, totalling 8 MB)
-
- Utility Version Time (sec) Options
- ------- ------- ---------- -------
- 1. LX/020 1.00 92.45 LX020 >nil: -q t
- 2. LX 1.00 95.23 LX >nil: -q t
- 3. LhA 1.38 103.72 LhA >nil: -q t
- 4. LZ 1.92 115.67 LZ >nil: -N t
-
- Comments: LX and LX/020 show their speed, a combination of optimised assembly
- language, and asynchronous disk i/o.
-
-
- C. Test 3
-
- Test one large file in RAM:
- (410K archived, 1500K decompressed, -lh5-)
-
- Utility Version Time (sec) Options
- ------- ------- ---------- -------
- 1. LX/020 1.00 4.93 LX020 >nil: -q t
- 2. LX 1.00 5.35 LX >nil: -q t
- 3. LhA 1.38 5.42 LhA >nil: -q t
- 4. LZ 1.92 10.98 LZ >nil: -N t
-
- Comments: Testing entirely in RAM, the asynchronous disk i/o advantage of LX
- is nullified, and, in fact, becomes a deficiency, although it
- remains faster than LhA.
-
-
- D. Test 4
-
- Test one large file in RAM:
- (410K archived, 1500K decompressed, -lh1-)
-
- Utility Version Time (sec) Options
- ------- ------- ---------- -------
- 1. LX/020 1.00 12.25 LX020 >nil: -q t
- 2. LX 1.00 12.75 LX >nil: -q t
- 3. LhA 1.38 15.34 LhA >nil: -q t
- 4. LZ 1.92 22.35 LZ >nil: -N t
-
- Comments: LX and LX/020 are far faster at decompressing -lh1- archives.
-
-
- E. Test 5
-
- Test all files in archives on DF0:
- (1 -lh5- archive, total 817K)
-
- Utility Version Time (sec) Options
- ------- ------- ---------- -------
- 1. LX 1.00 55.22 LX >nil: -q t
- 2. LX/020 1.00 55.30 LX020 >nil: -q t
- 3. LhA 1.38 80.68 LhA >nil: -q t
- 4. LZ 1.92 96.27 LZ >nil: -N t
-
- Comments: Demonstrates the advantage of LX's asynchronous disk i/o.
-
- As a sidenote, here are the stats for the 'copy' command
- (copy the archive from DF0: to RAM:)
-
- Utility Version Time (sec)
- ------- ------- ----------
- Copy 38.1 39.21

- ==============================================================================
-
- The above benchmarks were performed using:
-
- Amiga 3000 (25 MHz 68030)
- 6 MB Fast RAM, 2 MB Chip RAM
- 52 MB Quantum LPS
-
- All archivers and the timing program (RTimer) were in RAM:
-
- All console output was suppressed in all tests.
-
- The computer was re-booted between each test to avoid memory fragmentation.
-
- The Data and Instruction caches of the 68030 were enabled, as was BURST mode
- (for both Data and Instructions).
-
- These benchmarks provide a very general idea of the speed improvement of LX
- over other archives. Your mileage will vary.
