-T
Perform timings of cache reads for benchmark and comparison
purposes. For meaningful results, this operation should be repeated
2-3 times on an otherwise inactive system (no other active processes)
with at least a couple of megabytes of free memory. This displays the
speed of reading directly from the Linux buffer cache without disk
access. This measurement is essentially an indication of the
throughput of the processor, cache, and memory of the system under
test. If the -t flag is also specified, then a correction factor based
on the outcome of -T will be incorporated into the result reported for
the -t operation.

-t
Perform timings of device reads for benchmark and comparison purposes.
For meaningful results, this operation should be repeated 2-3 times on
an otherwise inactive system (no other active processes) with at least
a couple of megabytes of free memory. This displays the speed of
reading through the buffer cache to the disk without any prior caching
of data. This measurement is an indication of how fast the drive can
sustain sequential data reads under Linux, without any filesystem
overhead. To ensure accurate measurments, the buffer cache is flushed
during the processing of -t using the BLKFLSBUF ioctl. If the -T flag
is also specified, then a correction factor based on the outcome of -T
will be incorporated into the result reported for the -t operation.

hdparm is a Linux utility for viewing/manipulating various
IDE drive and driver parameters. Most systems can benefit
from improved performance using a command sequence similar to this:

#!/bin/sh
for d in /proc/ide/hd* ; do
if [ `cat $d/media` = 'disk' ]; then
hdparm -qm8 -qu1 -qc1 -qd1 -qW1 /dev/${d##*/}
elif [ `cat $d/media` = 'cdrom' ]; then
hdparm -qu1 -qd1 /dev/${d##*/}
fi

やっと、udma5が使えるようになりました。

気づかなかったけど、VIA VT82* South Bridge 使ってる場合、
RedHat7.2、付属のドライバ(via82cxxx.o)ではudma3/4/5が使えないみたい。
より新しいカーネルのドライバを使うと良いと思います。

(RedHat7.2のカーネルソース持ってる人は、
linux/drivers/ide/via82cxxx.c の436行目、
via_80w = 0;
っていうのをコメントアウトするとうまくいくかもしれません。
見たかんじ、これがケーブルの検出を無効にしてるみたいなので…
責任は持てませんが、私の場合はうまく動いるみたいです)

う〜ん。読み込み自体はそこまで変わらないと思ってたYo!
けど、BarraIVとU6って、7200/5400rpmぐらいしか違わないような…

うーむ、U6 でも 23M でるのか。俺は BX なためか
11.25 しかでなかった。
# 2年以上昔の IBM のほうが 16.89 で速い。

PenIII + VT82c586B + マクの80G とか IBM DTLA とか色々で
どうやっても 16MB/s あたりで頭打ちになる。
over 20MB/s ってどんな環境で出るの?
ATA66 で使ってるけど、ATA100 だと出る?
5400rpm だとダメで 7200rpm だと出る?

CPU とかﾁﾌﾟｾﾄの情報もｷﾎﾞﾝ

やっぱりサウスの責任かなぁ。
CPU は k6-III と Pen3-700 で hdparm -t の数値ぜんぜん
変わんなかったんだよね(サウスは一緒)。だから CPU は多分かんけいない。

hdparm -I で見ると /dev/hdc は udma4 に * が付くので ATA66
になってると思う。/dev/hda のほうはケーブルが ATA33 用なので
udma2 のままでいい。
実は ATA100 用ケーブル繋いだ /dev/hdc を udma4 で使ってみて
ぜんぜん改善しなかったので /dev/hda のほうを udma4 化する気力を
なくしてる ...

128 ：124：02/12/08 13:57 ID:3ofuvD+J.net

129 ：名無しさん＠Ｅｍａｃｓ：02/12/08 14:31 ID:cqe9VQcn.net

もしかすると、カーネルの問題かもしれず。

/usr/src/linux/drivers/ide/via82cxxx.c

の中で、無条件に via_80w に 0 を入れている場面があれば、犯人はカーネルです。
変なパッチが当てられてると思うので、そのパッチを抜いて再構築ですな。

132 ：123：02/12/12 08:41 ID:8b2/Odzj.net

のぉ、厨にわかるよう説明するの下調べが面倒臭い。。。

133 ：123：02/12/12 22:02 ID:8b2/Odzj.net

自分のIDEコントローラの調べ方：
* PCI_IDE: unknown IDE controller on PCI bus xx device xx, VID=xxxx, DID=xxxx

対応してない(unknown)なコントローラなら、VID=xxxx DID=xxxx として
Vendor、Deviceの各IDが表示される。

置換元のDeviceの調べ方:
linux/drivers/pci/pci.ids
や
http://pciids.sf.net/
を見て、旧世代のIDEコントローラのIDを探す。

* (VID)8086 (DIV)244b (Desc.)82801BA IDE U100

今回はこのICH2 UDMA100コントローラを生贄にしてみようか。

実際に置換する：
linux/include/linux/pci_ids.h内で、先の置換元を探すと

#define PCI_DEVICE_ID_INTEL_82801BA_9 0x244b

とある。これを書き換え。
#define PCI_DEVICE_ID_INTEL_82801BA_9 0xXXXX
(DID:244b->XXXX)

わが国のＩＴはユーザに使用法を十分説明する時間がありません。
このため、初心者がベテランに疑問についてたずねる光景を目にすることがあります。
しかし本来は事故（情報漏えいなど）が発生した場合の責任は、
接続業者、サーバ運営者、システムを開発したエンジニアにあります。
メーカあるいは購入店にたずねるべきです。
利用者の仕事は自治（掲示板の秩序を守ること）です。助言を行ってはなりません。
素人が専門技術に言及するのは「親切」ではありません。「無責任」です。
海外のプロフェッショナルは、「私の仕事ではない」と答えるはずです。

>>363のシステムドライブにOCZのMLCな60GBのSSDをゲット
さっそくCentOS5.2(x86_64)を入れてhdparm実行してみた。

# hdparm -tT /dev/sda

/dev/sda:
Timing cached reads: 22780 MB in 1.99 seconds = 11423.06 MB/sec
Timing buffered disk reads: 328 MB in 3.01 seconds = 108.82 MB/sec

とりあえずsshで入れる環境まで作って今日はおしまい。

起動はメチャ速くなりました。
要らんモジュールは削ってるけど、それでも速いです。
躊躇せず再起動できます。

まだあまり使い込んでるわけではないので、アレですけど
read は速くて write は期待したほどじゃない感じでしょうか。
tar の展開とか遅いなあって感じが、なんとなく。
ただ、これは気のせいかもしれません。
