pgAdminはリモート操作で非常に遅い

10

私の開発サーバーにリモート接続しているローカルのpgAdminからこのクエリを実行します。

select * from users order by random() limit 1;

それは17秒間ハングし、表示されます

Total query runtime: 148 ms. 
1 row retrieved.

また、テーブルを右クリックしても、すべての操作でハングします。

その後、RDPを介して接続し、同じpgAdminバージョンで同じクエリを実行しますquery time: 32 ms。これにより、で結果がすぐに表示されます。

次に、ローカルのpgAdminからクエリを再度実行します。

Total query runtime: 337 ms.
1 row retrieved.

サーバーに対して130ミリ秒のpingを実行しています。FTP経由でファイルをかなり高速にアップロードできるので、接続速度は十分すぎるはずです。

ローカルのpsqlで実行したときの同じクエリは、接続時間を含めて数秒で終了します。

ローカルのpgAdminでローカルのdbコピーを使用した同じクエリもすぐに終了します。

pgAdminのバージョンは1.20.0です。最新の1.22でも確認しました-まだ同じです。

pgAdminを高速化するにはどうすればよいですか？

psqlは正常に動作することに注意してください。そこには同じ待ち時間がありません。

@dezsoいつでも、F5キーを押してクエリを再実行します。「常に」には十分ですか？

からの抽出pgadmin.logは、結果の各出力列pgadminに対して、カタログに対して2つのクエリを実行することを示していoidます。

あなたの抜粋では、私が正しく数えているならば、そのようなクエリの総数はのようです106。

のping時間148 msから、サーバーへのラウンドトリップの最小時間がであると仮定しましょう148 ms。したがって、この一連のクエリにかかる最小時間は148 x 106 = 15688 ms、または15.6 s

一方、コマンドラインpsqlクライアントはこれらのクエリを実行しないため、15.6pgadminの少なくとも数秒前に終了することが期待できます。

私はpgadminでそれを無効にするオプションを知りません。開発者に問い合わせるか、最新バージョンがあるかどうかを確認することをお勧めしますが、昨年と同様の質問がメーリングリストで行われ、どうやら応答：

長いクエリ結果のレンダリング（pgadmin-supportアーカイブ内）。

これはpgAdminの残念な実装の詳細です。IN(...)構成または配列で渡されたOID型のリストを使用して、単一のクエリですべての結果を取得できます。また、これらの結果をキャッシュし、すでに確認したOIDでクエリを繰り返すこともできません。
