Hi All,
SL 6.2 64 bit
Has anyone noticed that their USB 2.0 ports are really, really
slow?
If I need to copy anything substantial to my USB 2 sticks, I
boot into Fedora Live 17 Xfce 64 bit CD. Then it goes about 20
times faster than under SL 6.2.
Anyone have a work around?
Many thanks, -T
It might help if you mentioned what USB hardware, exactly, you
are using, and what you're doing on it. Flash drives? External
Storage? Do you re-arrange your attached devices when you boot to
Fedora 7?
The stick usually is a Kanguru Flash Blue II (20 MB/s write, 24
MB/s read). But sometimes it is a Verbatim (same speed as the
Flash Blue).
I've experienced this on older Fedora releases as well as openSUSE;
it's only been recently fixed in upstream kernels (since 3.3) and the
fix probably hasn't been backported to the RHEL kernels yet (it's
probably not a priority for enterprise Linux use cases)

"Compaction combined with Transparent Huge Pages can cause significant
stalls with USB sticks or browser"

I think you called it. Thank you! I will have to hold my
nose until they back port.
