High CPU usage with iTunes with Windows XP Guest — at Initial Version
| Reported by: | Paul | Owned by: | |
|---|---|---|---|
| Component: | other | Version: | VirtualBox 2.1.4 |

| Guest type: | Windows | Host type: | Linux |
Description
Host: Ubuntu 8.04 32 bit on AMD 2.4 Ghz, 2 gigs RAM running Virtualbox 2.1.4 Guest: Windows XP SP3 with 512MB RAM allocated
If iTtunes is running (idle) CPU usage on the Ubuntu host hovers at around 60%. CPU usage on the XP guest is minimal. If I try to do anyting with iTunes, CPU usage on the Ubuntu host if peaked at 100%, which maked iTunes very slow and unusable. If I close iTunes, CPU usage drops to nothing.
Same occurs on laptop with dual core 2.5Ghz and 4 gigs of RAM. running Ubuntu 8.04 64 bit as host. CPU usage hovers at around 40% when iTunes is idle in the XP guest
Tried the following without any success.
- disable iTineshelper (found this in another post)
- disable any additional apps/services such as antivirus
Had the problem since I 1st installed VB 2.0.6, hopped the newer versions would have fixed the problem.
Logs show the following at times when starting and closing iTunes
00:01:12.202 PIT: mode=2 count=0x4ad (1197) - 996.81 Hz (ch=0) 00:01:49.799 PIT: mode=2 count=0x2ead (11949) - 99.85 Hz (ch=0) 00:03:45.745 PIT: mode=2 count=0x4ad (1197) - 996.81 Hz (ch=0) 00:04:33.132 PIT: mode=2 count=0x2ead (11949) - 99.85 Hz (ch=0)
