ドル高圧力に耐えかねて、プライベート用のサーバを AWS EC2 から ConoHa VPS に移行したのが二ヶ月ほど前のこと。それが先日、コンパネをいじっていたらメニューの一番下に「バージョン切替」というボタンが出来ていて、「ナニコレ？」とポチってみたら「新バージョン(Ver.3.0)と旧バージョン(Ver.2.0)の管理画面を切り替えることができます」とのダイアログ。
実際に切り替えしてみたらサーバリストに契約中のものが表示されなくなったので、先だって立てたサーバは Ver.2 だったようです。調べてみたら 12/22 までのリニューアルキャンペーンが行われているので、ここ暫くの間にサービスがメジャーアップデートされたってこと？ アナウンスメールも来てないし、聞いてないぞそれ。
結局 V2 と V3 の違いはよく分かりませんでしたが、サービスの基本形は従来とさほど変わらないようなので、実際にサーバを立てて両者の基本性能を比較してみることにしました。私が立てたサーバのタイプは「メモリ 1GB/CPU 2Core」(Ubuntu 20.4 LTS)なので、これと同様のものを。V3 でサーバ追加しようとしたら Ubuntu に 22.04 LTS が追加されてますね。今どき 20 系はちょっと古いんでね？ と思ってたのでこれは嬉しい。折角なのでこちらを選択してポチッとして、さてリモートログイン。
まず lscpu で両者のプロセッサを確認。
v2:~$ lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian Address sizes: 46 bits physical, 48 bits virtual CPU(s): 2 On-line CPU(s) list: 0,1 Thread(s) per core: 1 Core(s) per socket: 1 Socket(s): 2 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 85 Model name: Intel(R) Xeon(R) Gold 6230 CPU @ 2.10GHz Stepping: 7 CPU MHz: 2095.078 BogoMIPS: 4190.15 Hypervisor vendor: KVM Virtualization type: full L1d cache: 64 KiB L1i cache: 64 KiB L2 cache: 8 MiB L3 cache: 32 MiB NUMA node0 CPU(s): 0,1 (後略)
v3:~$ lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Address sizes: 40 bits physical, 57 bits virtual Byte Order: Little Endian CPU(s): 2 On-line CPU(s) list: 0,1 Vendor ID: GenuineIntel Model name: Intel Xeon Processor (Icelake) CPU family: 6 Model: 134 Thread(s) per core: 1 Core(s) per socket: 1 Socket(s): 2 Stepping: 0 BogoMIPS: 4000.00 (中略) Virtualization features: Virtualization: VT-x Hypervisor vendor: KVM Virtualization type: full Caches (sum of all): L1d: 64 KiB (2 instances) L1i: 64 KiB (2 instances) L2: 8 MiB (2 instances) L3: 32 MiB (2 instances) (後略)
なるほど、プロセッサは Xeon Gold 6230 から Icelake に変わったと。最近のプロセッサ事情には疎いので、性能的にどう違うのかはよく分かりません。なので、sysbench でベンチマーキング。
v2:~$ sysbench cpu run sysbench 1.0.18 (using system LuaJIT 2.1.0-beta3) Running the test with following options: Number of threads: 1 Initializing random number generator from current time Prime numbers limit: 10000 Initializing worker threads...

すごいです。「CPU speed」は約3.7倍の数値。ではメモリ操作は？

プロセッサの能力向上のせいでしょうか。転送速度が1.6倍に向上してます。次にファイル入出力を。

総合的に1.3倍程向上してるようです。最後に MySQL での入出力を。事前の準備(CREATE DATABASE や GRANT 等)については省略します。
v2:~$ sysbench --db-driver=mysql --mysql-user=sysbench --mysql-password=******** --mysql-host=localhost --mysql-db=sysbench oltp_read_write run sysbench 1.0.18 (using system LuaJIT 2.1.0-beta3) Running the test with following options: Number of threads: 1 Initializing random number generator from current time Initializing worker threads...

こちらも2.6倍の向上というご機嫌な結果に。
まぁ単純なベンチマーキングなので、アプリケーションの体感等にどの程度現れてくるかは分かりませんが、これなら V2 ユーザは V3 に移行して損はないようです。ConoHa さんももうちょっと積極的にプッシュしたらエエのでは。
