Coherence mode very slow in Parallels 4

Hi

I am currently using Parallels 4 to run Windows Vista Ultimate 64 bit. When I run Parallels 4 in window mode or full screen mode, the performance is usually acceptable.

However when I run it in coherence mode both the start up and suspension takes significantly longer. Also even after the VM wakes up from suspension, the VM is unresponsive for a while.

Does anyone have this issue? Could it be because I have only allocated 1 Gb of memory to the VM? I am running Parallels on an iMac 2.16GHz with 2Gb of RAM.

Thanks.
 
Hi HoYoung Kang,

We will reinstall Parallels Tools.

1) Go to Control Panel => turn off Windows Firewall and also Anti virus.
2) Disable the Parallel Internet Security (Kaspersky).
3) Go to Add or remove Programs => Remove Parallel tools completely.
4) Install Parallel tools
5) Restart the Windows Operating System.

Check if it works fine now.
