|
Latest TCP script at the bottom (3180 bytes).
|
||
|
|
4 tests: 64bit dual core Athlon tmpfs / disk (reiserfs) - 60MB/s,
|
||
|
|
32bit Athlon tmpfs / disk (reiserfs) - 55MB/s
|
||
|
|
Both machines were idle -- used for testing only.
|
||
|
|
Tarball and extracted files were on different physical devices.
|
||
|
|
Test data: linux 2.6.22/3 kernel sources for memory operations,
|
||
|
|
for the other data average file size should bring enough info.
|
||
|
|
|
||
|
|
2 x [...] processor means 1 processor with 2 cores (2 entries in cpuinfo).
|
||
|
|
Archive format is set to pax (Joerg).
|
||
|
|
Let's end with it. I only wanted to send You a new version of TCP script :-).
