So I modded my bcm5352 and the speeds are better than the mmc sdhc driver floating around, but still pretty slow for usb. This is on the usb 2.0 channel with a run of the mill flash drive.

What router?

I guess what I was really looking for was the discrepancy between the speed of the flash memory and usb in the buffered read test, i.e.

"-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. "


[code]root@fscd@#$g54t:~# hdparm -tT /dev/scsi/host0/bus0/target0/lun0/disc

Timing cached reads: 116 MB in 2.00 seconds = 58.00 MB/sec
Timing buffered disk reads: 4 MB in 4.70 seconds = 871.49 kB/sec

root@fscd@#$g54t:~# hdparm -tT /dev/mtdblock/1

/dev/mtdblock/1:
Timing cached reads: 104 MB in 2.04 seconds = 50.98 MB/sec
Timing buffered disk reads: 6 MB in 1.95 seconds = 3.08 MB/sec

root@fscd@#$g54t:~# hdparm -tT /dev/mtdblock/2

/dev/mtdblock/2:
Timing cached reads: 112 MB in 2.00 seconds = 56.00 MB/sec
Timing buffered disk reads: 4 MB in 1.15 seconds = 3.48 MB/sec

Do you have details on how you did the mod? Maybe some pics too?

It is actually in this section. The thread I looked at the other day: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=64931

The usb works fine, but I guess I just wanted to know where the bottleneck is, and how to improve upon it if possible. I am limited by a 5v adapter's 8.75 watt limit rather than using a regulator, which is more than ample output for the router and a couple spec draw usb devices, but am unable to overclock with the stability I once had prior to the usb mod (when a device is connected). I will underclock to see how much it affects that number I am fixated on understanding.

edit: it no longer likes either overclocking or underclocking when the usb is plugged
