We are pleased to announce the release of OSv 0.10 Alpha Release.
Some of the noteworthy performance improvement are in this release are:
- Implementation of Timer Wheel
- Improve TCP Tx performance by about 10% with virtio::net not using indirect buffers
- Improve TCP Tx performance for small packets by about 5% with avoiding excessive kicks
- Improve ZFS performance enabling real-time by default when creating ZFS data-set
- Improve ZFS mount time when previous instance has performed I/O
Some of the noteworthy additions are:
- New REST API
- Query thread status
- Activate/Deactivate trace points
- Controlling sampling profiler *Get environment variables
New API schema is available here
- libosv.so, a library containing all visible OSv symbols. Useful for loading as a module for JNI or JNA users.
more applications are enabled on OSv. Few of the latest are:
- CRuby
- OpenDayLight
Work on AArch64 port continue to progress, few of the latest updates:
- support for ELF lazy function resolution
- QEMU system emulation now boots our image successfully, after fixes both here and in QEMU.
- more complete pl011 console support (now takes inputs)
- There is a performance regression on GCE. We are looking into it and expect to have a fix release in the near future.
- Images of the new release are available at osv.io/downloads and using capstan search
- EC2 community AMI are available here
