Time out on reading files and running SQL queries

[Neil Martin]

I am running a Windows XP VM and a Windows 2003 server VM on an Ubuntu 10.04 host. I was running VirtualBox 3.2.12 but got an alert that a new version was available so decided to try upgrading.

I ran into two problems. 1 - reading an Excel spreadsheet with many worksheets (about 1.6 M in size) would time out. I had been using this regularly under 3.2.12. 2 - running SQL queries in unit tests from the XP machine to the 2003 server VM would time out. Running the queries manually showed that the results were being returned very slowly. Initially I would get about 150-200 records and then further results at a rate of about 10-20 records every 30 seconds or so. This was on a small table with 2500 records total and a small record size (5 columns, 3 string fields of less than 20 characters each and 2 decimal fields).

I reverted back to version 3.2.12 to resolve these problems.

I also noticed that ticket #8388 seems very similar although it appears to be for a different combination of host and guest o/s.
