Re: [Bug 216878] Re: Slow disk transfer rate on Hardy
Hi Teej,
if you take a look at the bug report, you'll discover that this
but is STILL present in Intrepid.
There hasn't been any activity since nobody from the bug squad ever
replied to this bug, but I can confirm definitely that this is there.
Let me know what kind of info do you need to spot the problem.

[Bug 216878] Re: Slow disk transfer rate on Hardy
The problem with 8.04 Hardy Heron's use of libata and improperly setting DMA characteristics of systems is inhibiting effective use of solid-state media in systems. On a number of systems I have confirmed that this does not exist on Feisty (7.04) and Dapper (6.06) systems where full-speed is attained on Flash-Memory-based systems.

[Bug 216878] Re: Slow disk transfer rate on Hardy
I'm seeing slow disk transfers with Hardy (8.4.1) on a server. Windows 2003 server on older/slower hardware is performing better. I need to improve the Ubuntu server performance! :) Here are some examples of hdparm results on my Ubuntu Hardy server. These are from a RAID-5 array on an LSI MegaRAID 320-2E SCSI controller with 4x Seagate 15k rpm drives. /dev/mapper/sdX_crypt: Timing cached reads: 1378 MB in 2.00 seconds = 688.89 MB/sec Timing buffered disk reads: 166 MB in 3.01 seconds = 55.12 MB/sec /dev/mapper/sdX_crypt: Timing cached reads: 1368 MB in 2.00 seconds = 683.69 MB/sec Timing buffered disk reads: 170 MB in 3.02 seconds = 56.37 MB/sec I have all the relevant info (dmesg, lspci, lsmod, hdparm, bonnie++ output, etc.) I will post it here if requested.
