Benchmark USB performance #6

Open yuvadm opened 11 years ago

yuvadm commented 11 years ago

Some buffer underruns have been noted (e.g. while running an async rtl_test).

USB performance in VMs is notoriously slow, and might be problematic in the future.

On the readme it is mentioned "enable USB EHCI mode, which is required for rtl-sdr usage" I seem to have underruns regardless if option is enable. Perhaps a configuration issue on my end? Do you see the underruns any different when USB EHCI enabled?

@geekskunk which VM are you running? IIRC VMware stuff should perform better than VirtualBox

geekskunk commented 9 years ago

@yuvadm Have run only VirtualBox with extension pack for USB 2.0. I started there as I saw a few anecdotal mentions of better performance than VMware for SDRs in VMs, but perhaps I'll go compare with VMWare. (Your readme.md file mentioning USB EHCI was the most specific, so was hoping I may have been missing a setting to optimize it.)
