Hi Pavel,
Just did some benchmarking; results below.

What is the performance difference between safe and unsafe version?
File size: 256K
- Following as tests for original test code - not any kernel port of this.
- Test with each block size repeated 5 times - taken avg. of these 5 runs.
- Same file used for each test.
- Used lzotest utility (included with LZO 2.02) for testing.
Blocksize Comp* DU* DS* Speed%
4 59.356 211.526 195.260 7.689
8 54.623 202.712 188.369 7.075
16 50.342 196.482 183.988 6.358
32 47.499 189.800 177.455 6.504
64 44.148 178.724 167.201 6.447
128 42.125 170.229 159.257 6.445
256 41.830 155.035 146.115 5.753
* All speeds in MB/sec
Comp = LZO1X-1
DU = Decompress (unsafe)
DS = Decompress (safe)
Speed% = ((DU-DS)/DU)*100
I have yet to see how the kernel ports compare against this original version.
Cheers,
Nitin
