Virtualbox Settings & Performance

I'd like to hear from other people and your experiences. If you're having poor performance, try checking your settings compared to this. If you've found something that works better ... please share -- but your system specs are also important. Also, please post your settings, or jump in IRC at #drupalpro

EDIT: I've updated video driver settings

Recommended Settings

Requirements: Virtualbox v 4.1.18 (or newer)

Settings > System > Motherboard

Base Memory >= 1020MB RAM (more=faster) -- (I regularly run with only 1020MB)
Extended Features
[x] Enable IO APIC (I've been playing with this ... and Ubuntu might not care)
[ ] Enable EFI (special OSes only) -- DONT ENABLE THIS
[x] Enable clock in UTC time
[x] Enable absolute pointing device

Settings > System > Processor

Processor(s): more = faster (mine is 4CPUs)
Execution Cap: ??? no recommendation. (mine is 100% -- CPU is only used as needed.)
Extended Features:
[x] Enable PAE/NX (THIS IS IMPORTANT FOR 32-BIT Ubuntu 12.04 -- and should be deselected on a 64-bit image -- future versions of DrupalPro only -- current beta's have only been 32-bit)

Under Settings > System > Acceleration

[x] Enable VT-x/AMD-V
[x] Enable Nested Paging

Under Settings > Display > Video

Video Memory = 64MB+ -- or MAX per your system (I find maxing out makes for snappier system)
Monitor Count =1 (if you adjust, you might need to adjust Video Memory)
[ ] Enable 3D acceleration <-- Only enable if host has good video driver support
[ ] Enable 2D Video Acceleration (DO NOT CHECK -- doesn't work in Ubuntu)

Under Settings > Storage > SATA Controller

[ ] Use host I/O cache (DO NOT CHECK THIS -- will slow down DrupalPro)

If you're using SSD drive, for each drive:
[x] Solid-state drive (if you're not using SSD, don't enable)

My System Specifications

Acer Aspire S3 ultrabook. Purchased in Feb~Mar 2012.
CPU: i7-2637 @1.70Ghz
MEM: 4GB (3.85 usable to OS)
OS: Win7 64-bit Host / Dual boot with Ubuntu 12.04 64-bit

I like it, but wouldn't buy it today -- only has USB2 -- and I prefer a larger monitor. Still a great deal compared to Apple Air.
