What's your experience been running it in production? Any gotchas?
- Titanous 12y agoWe use it to share filesystems into QEMU/KVM VMs, so far zero issues, but it's not a performance-constrained use case. I do have some plans to do benchmarks for another use case that's more performance intensive, but it's buried in my backlog right now.
- antocv 11y agoCan you do a simple time sh -c "dd if=/dev/zero of=testfile bs=8k count=11000"; rm testfile "performance" test? Also do the read test on a really big file, first from your host - so the file will get cached, then from within the qemu-vm where virtfs plan9 is mounted, dd if=bigfile of=/dev/null Please, I want to confirm its not only my machines suffering from really totally shitty read/write performance thru virtfs?
- antocv 11y agoIts performance for me was 500% slower than NFS which was only 30% slower than direct IO. No time to investigate.
