Thanks for the insight. I shall bear this complexity in mind when
pondering further.

raw USB speeds are faster but not fast on OpenBSD.

ntfs-3g uses fuse(4) which has its own performance issues.

msdosfs has also known performance issues.

The speed of USB devices my vary a *lot* as well.

So to resume the situation you have at least 3 different subsystems
where performance could be improved on top of pieces of hardware of
different quality.

Everything can be improved, it's a matter of dedication ;)  But make
sure you don't compare oranges to apples.

I'll send some info as soon as I get a chance. How are you measuring
speeds?

hmm. I am seeing slow writing on usb2. Perhaps it is exacerbated on usb3?

It seems there may be a speed issue of some kind. A past thread
mentions raw devices being fast but doesn't ntfs-3g use raw access.

ntfs-3g is the slowest then msdos gets around 2200 Kilobytes/s.

The same msdos stick gets 12000 Kilobytes/s on Win 10.

FFS is faster. Strange to me that usb hdd have always been fast with
any filesystem. I will try a ntfs-3g usb hdd on a recent snapshot.

I will try with softdep and noatime.
It's just -current, after all.

Re: Still having super slow speeds with USB 3 flash.

2018-03-06 Thread Chris Bennett 
Then I need to install the latest -current and make a bug report.
I've had the same problem with several USB 3 flashes on different
computers. I was hoping the problem would eventually get fixed.

It's a Sandisk Ultra Fit? I will look for one or order one.
I have wondered if the actual flash drives themselves were the problem.

If anyone reading this can tell me what info I need to include in the
bug report, I will add it.

Did you do anything special with swap or /tmp? I want to duplicate your
setup more or less.

By the way, I can't manage to get UEFI to work on USB disks. Did you?

Thanks, glad to know it is possible to have things work properly.

reordering libraries is slow enough to finish a cup of coffee.

Probably waiting on buffers would be my guess. I have witnessed those
delays on flash sticks.

I doubt it. What speed are you getting and what kind of memory. Even
class 10 SD isn't very fast at writing. Everything else being the same
compared to HDD, then I would look for faster memory?
