Long uses 4 bytes. Allocating 2*33554432 elements = 268435456 bytes of memory.
Using 262144 bytes as blocks for memcpy block copy test.
Getting down to business... Doing 10 runs per test.

I'm not sure if I'm doing this right, but it looks like the Sheevaplug beats all ARM chips (except
on FP) on the tests done at [1]. Looks like these tests heavily depend on the clock frequency.

Performance and compatibility issues with Shared Folders in Parallels Desktop build 9344

Parallels 內裝的是 Windows XP, 裝 Office 2010

 

從 Office 2003 移 .pst 檔給 2010 用的時候. 

會出現 Office 存取錯誤, 或是像是如下的錯誤

MS Office 2010 0x800703ee error
