VBox 2.1.0 on Solaris constantly opening iconv shared objects

Reported by: Paul Owned by:
Component: shared folders Version: VirtualBox 2.1.0
Keywords: performance Cc:
Guest type: Windows Host type: Solaris

Description

A VirtualBox Windows 2003 guest performing a Visual Studio build on a shared folder is taking many times longer than the same build on a "local" guest filesystem.

Truss'ing VBox while this is happening shows the VirtualBox process repeatedly opening shared objects related to iconv() (every 100 uSec or so!). At bottom of this report is output from "truss -D -t\!all -topen -p <vbox-pid>".

This is normal for converting filenames from one codeset to another.

comment:2 by Frank Mehnert, 14 years ago

Actually this will be fixed in the upcoming release 3.2.0.
