Increased performance of emulated NVMe devices

August 23, 2016 by Helen Fornazier  |   Blog

Nowadays, in Google Cloud Engine (GCE), it is possible to attach a local SSD with the NVMe interface to your virtual machine. Unfortunately, you only get a good number of iops (input/output operations per second) if you instantiate a machine with nvme-backports-debian-7-wheezy…

GStreamer Echo Canceller

July 08, 2016 by Nicolas Dufresne  |   Blog

For a long time I believed that echo cancellers had no place inside GStreamer. The theory was that GStreamer was too high level and would never be able to provide accurate enough delay information for any canceller to work.

Using the Linux kernel's Case-insensitive feature in Ext4

August 27, 2020 by Gabriel Krisman Bertazi  |   Blog

Last year, a (controversial) feature was added to the Linux kernel to support optimized case-insensitive file name lookups in the Ext4 filesystem. Here's a look at why this was merged, what improvements have been made since, and how to put it to work.
