lis3.5's Issues

are these old software's still maintained?

just wondering, have these very old repos still looked at or used, or are they a thing of the past?

Network performance deterioration with every next kernel upgrade

Just my 2cc:

I've ran a series of tests to measure network upload performance between 2 VMs

1. Linux guest pushing: dd if=/dev/zero bs=1024K count=5120 | nc -v 192.168.1.2 2000
   to
2. Windows guest (192.168.1.2) with netcat listening at 2000

Both VMs are sitting on the same host connected over vSwitch.
All linux guests were created equal (static RAM - 1024MB, 2 vCPU, with GUI)

I've noticed that the upload speed is deteriorating significantly with every newer kernel.
Older kernel results:
CentOS 6.5 (kernel 2.6) - 100 MB/s
Debian 7.3 (kernel 3.2) - 190 MB/s

Newer kernels demonstrate worse performance:
Fedora 20 (kernel 3.11) - 65 MB/s
Ubuntu 14 (w kernel 3.13) - 40 MB/s
Debian 7.3 (upgraded to kernel 3.13) - 90 MB/s

Hyper-V Doesn't Build on Linux Kernel Because Function Required for Hyper-V Build Was Changed

Hyper-V calls function utf8s_to_utf16s and passes three arguments, the updated function requires passing five arguments.

Mainline kernel roadmap

Guys, pls, share your roadmap:

1. When do you expect 3.5 to be a part of main line kernel?
2. Is there any plans for Linux Gen2 VMs?
