Hello hackers... I've spend some time working on GEOM Gate, so...
Cache was implemented, but only for reading (cache for write requests
isn't good idea here, IMHO).
Many workers can be used now. This will help to split requests.
Requests are queued and always worker with minimal number of pending
requests is choosen.
Workers can be added at run-time with '-r' option.
ggd(8) use now NFS-like exports file. Sample entries:
192.168.0.3 RD /dev/acd0
192.168.0.4 RW /test.img
192.168.0.5 RW /dev/ad0s1a
I've also wrote some manual pages:
- gg(4),
- geom_gate(4) (exists, but isn't finished yet),
- ggc(8),
- ggd(8).
There are few sysctls that could help in performace and memory consumption
tuning and more to come.
TODO.
Errors handling needs more work.
Maybe UDP (for now transport is done via TCP).
Per-device sysctls created automatically.
Regression tests.
Performance benchmarks.
GEOM Gate is avaliable at:

See you all at BSDCon 2003!:)
