Hi Oleg and others!
I'm referring to Olegs speedup patch for 2.4.19-pre5+ - oh maybe it was
a modified one for -pre6 (not to Chris' more actual version). In the
attachment there are some beautified results on my backup cycle.
The new file size distribution statistics according to the alteration to
the first known one are available upon request, Oleg, but the rate
differences are really similar, so I assume you won't need them.
I removed the iicache patches.
I found these values very nice!
Bye,
Manuel

Data:
-----
Previously fresh backupped/copied partitions (shown are copy-back-times
"without fragmentation"). Mount options "-o noatime,notail"
Settings:
--------
AA VM and AKPM max_bomb_segments settings same as in my first private
mails, see information below, only disk content "slightly" differing.
Kernel:
-------
Still Kernel 2.4.19-pre5, aa.vm-33 + some other aa.patches,
akpm.read-latency-2 applied, some standard kernel values are altered
with powertweak-0.99.4.
Hardware:
---------
933MHz-PIII-noname/Clevo.tw-notebook, one of the partitions'
counterparts only ide1-tree udma(33), first one ide-0 udma(66),
512MB RAM.
Circumstances:
--------------
Only KDE 2.2.1 running (untouched) additionally.
No new bitmap allocator, yet.
CONFIG_REISERFS_PROC_INFO enabled.
That latest backup copies consume about 20..30% (varying) CPU. dd...s take
about 22%, ksysguard approx. values
