唔識睇英文咩 段news release咪講左

好混亂

究竟係fix 到但降效能定係fix 唔到又降效能

Fix唔到行佢個patch 降自己效能做乜9

實際上fix唔到 patch係兜路行
2018-01-05 10:34:57
設計缺陷

8代降幾多 9代幫你升返

The problem with this isolation is that some programmers are reporting performance hits after systems are patched. The Register reports that the slowdowns could be between 5 and 30 percent depending on the exact Intel processor. While Linux patches have been rolling out over the past month, a Windows 10 patch is not yet available. Some are speculating that Microsoft will deliver this in an upcoming Patch Tuesday, as the company started separating the NT kernel memory with Windows 10 beta builds in November. “We have nothing to share at this time,” says a Microsoft spokesperson, in response to a query from The Verge.

VM / PCIE SSD先會中伏。
啲cloud provider / SQL etc就食哂屎,一般人又點會有事。

啱啱試咗,其實冇咩分別



Patch前



Patch後

家用冇咩大影響
只影響 ssd速度 同 vm 效率
2018-01-05 11:21:09
其實有睇tech test 都係話heavy IO loading/VM 先會有performace degrade
日常用係無事 但啲報紙都係狂執住呢樣野做標題
2018-01-05 11:21:33
SSD都冇乜影響...
我諗影響SSD都係超級大量I/O 先會有分別...
2018-01-05 11:25:59
我run前後test基本上只係得 4k random R/W 跌咗2.8%
其餘所有test 快/慢咗不足1% 都係within margin of error..

正解,即係唔用個 hardware virtualization technology,當係 BIOS disable 咗囉。個個 VM 要排隊單線行,唔慢先奇

理得佢
係咪煙條都已經誠信破產
下一次upgrade 就跳槽
2018-01-05 11:50:29
好多玩家都用VM多開打機、掛機
2018-01-05 11:51:30
真patch 未出
但呢度已經有人響度試
2018-01-05 11:54:13
睇zen2同9代效能比較
如果9代仲有呢d on9 bug就唔會考慮
2018-01-05 11:55:50
誠信破產?
如果咁樣叫誠信破產
AMD執咗10世
2018-01-05 11:57:06
9代都應該有架喇

hw上面搞 再tape out 再mp
都要2-3年...
2018-01-05 11:58:38
係死雞撐飯蓋,關乜誠信事。
2018-01-05 12:00:20
D網話連firmware 都要update 係咪真?
2018-01-05 12:04:07
今年叫Zen+,下年先Zen2
2018-01-05 12:07:29
果個係另外一個bug
Intel Management Engine
要老母板bios update

有Intel news release唔睇,有第一水patch測試唔睇,走去睇兩日前既新聞
