2 SATA SSDs to NVME SSDs 这将是4倍以上的增加IO性能升级（实际用户体验肯定没有四倍）
3 网络带宽 1Gbit to 10Gbit （好像是为使用设备6个月以上的老用户准备的 我的英语水平捉鸡，大家见谅）
1270 v3到3900X 以及升频，性能会影响多少？？
New Year, New... Intel exploit? Sigh.
Since the launch of our KVM Slices, we have used Intel 1270v3 CPUs with SATA SSD storage. This setup has treated us well with performance that does not break the bank. Unfortunately, Intel CPUs have lost their performance advantage over the last 2 years due to design flAWS that have led to security exploits/vulnerabilities.
You would have most likely heard of these exploits/vulnerabilities by the names 'Meltdown', 'Spectre', and 'MDS'.
While these exploits/vulnerabilities can be mitigated in software, this comes at the cost of performance. Estimates show a performance loss of around 30% when these mitigatiONs are enabled (and even more if HT/SMT is disabled).
Today we are happy to announce a complete overhaul of all of our KVM Slice nodes to AMD Ryzen 3900X CPUs. Our originally advertised 3.5GHz clocks will increase to 3.8GHz with a boost clock of 4GHz+ (we are seeing an average boost clock of 4.1GHz on most cores). Storage will also be upgraded from SATA SSDs to NVME SSDs, which will increase IO performance by 4x or more.
Network connectivity will be upgraded from 1Gbit to 10Gbit. While your service will remain capped at 1Gbit in each direction, we are considering uncapping inbound speeds for long term customers (customers who have had an active service for >6 months for example). We haven't given this too much thought yet but many users have shown interest in veteran perks.
Last but not least, A+B power will be set up in Las Vegas to protect us from the Homer Simpsons that always seem to end up working on our power panels. This has been in the works for a while but has only recently become possible.
We have begun ordering equipment for Las Vegas and expect to be racking the new nodes in the next week or so. You will receive an email soon that will document when your VPS will be migrated. A reboot will be required upon which your Slice will automagically be migrated to our new nodes.
We expect to get New York done by early April and will be taking this opportunity to bring our Block Storage Slabs online with new network connectivity (ideally, NYIIX & Hurricane Electric). A new Juniper router will also be installed.
Luxembourg upgrades are for the moment up in the air, but we hope to complete them this year as well.
We thank you for your patronage and are excited to see what you think of our new nodes!
