| #17573 | fixed | Regression: "Use Host I/O cache" setting seems to be inverted in 5.2 => fixed in SVN/next maintenance | ||
| Description |
I believe that between 5.1 and 5.2 some change led to an inversion of the "Use Host I/O cache" setting. I mark this bug as critical as people that explicitly disable Host I/O caching to ensure data integrity in case of a power outage may now actually have Host I/O caching enabled and are in danger of loosing data in power outage/reset situations. Using VirtualBox for testing system installations I activate the Host I/O caching setting to increase performance when installing a lot of RPMs in the virtual machine, particularly because the VDI file on the host resides on a mechanical HDD. When switching from VirtualBox 5.1 to 5.2, I noticed a considerable slowdown. I measured the slowdown with an ansible playlist that brings a minimal system (installed with Fedora kickstart) to a production level system. The script spends most time on installing RPMs. Some stats of the RPM installation: Number of RPM packages before: 324 Number of RPM packages after: 1490 Total file size of all RPMs before: 734 MiB Total file size of all RPMs after: 3.9 GiB It is Fedora (guest) on Fedora (host). This is with the old VirtualBox 5.1, where everything worked as expected. Installation run on VirtualBox 5.1.32, "Use Host I/O cache" activated: real 7m38.936s user 0m19.646s sys 0m3.937s Going to VirtualBox 5.2 the effect of the setting seems inverted: Installation run on VirtualBox 5.2.6, "Use Host I/O cache" activated: real 52m17.548s user 1m22.884s sys 0m17.828s Installation run on VirtualBox 5.2.6, "Use Host I/O cache" deactivated: real 10m3.771s user 0m22.089s sys 0m5.119s And here I confirm that the test version is still affected: Installation run on VirtualBox 5.2.7, "Use Host I/O cache" activated: real 37m57.730s user 1m13.114s sys 0m15.521s Installation run on VirtualBox 5.2.7, "Use Host I/O cache" deactivated: real 11m1.805s user 0m29.377s sys 0m5.790s |
