The fix for bug #1618473 introduced a number of performance issues for MOS end users, since recent x86 extensions are no longer available for MOS compute's vCPUs. Here is the most important ones:
- aes
- pclmuldq
- x2apic
- avx (NOT avx2)
- ssse3, sse4_1, sse4_2
This problem can be critical for micro and nano instances and will affect customer experience (there are a number of complains in the web about cloud providers failing to provide some CPU instruction set extensions).
It is also worth mentioning that there is Ubuntu bug #1524069 with the same complaints. |
