pgAdmin działa bardzo wolno przy każdej operacji zdalnej

10

Uruchamiam to zapytanie z mojego lokalnego pgAdmin łączącego się zdalnie z naszym serwerem deweloperskim:

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

zawiesza się przez 17 sekund i pokazuje

Total query runtime: 148 ms. 
1 row retrieved.

wisi także na dowolnej operacji: nawet kliknięciu prawym przyciskiem myszy na stole.

Następnie łączę się przez RDP i uruchamiam tam to samo zapytanie w tej samej wersji pgAdmin, która natychmiast wyświetla wyniki query time: 32 ms.

Następnie ponownie uruchamiam zapytanie z mojego lokalnego pgAdmin:

Total query runtime: 337 ms.
1 row retrieved.

Mam ping do 130 ms na serwer. Szybkość połączenia powinna być więcej niż wystarczająca, ponieważ mogę tam przesyłać pliki przez FTP dość szybko.

To samo zapytanie uruchomione z moim lokalnym PSQL kończy się w ciągu kilku sekund z uwzględnieniem czasu połączenia.

To samo zapytanie w moim lokalnym pgAdmin z moją lokalną kopią bazy danych kończy się natychmiast.

Wersja pgAdmin to 1.20.0. Sprawdzone także w najnowszej wersji 1.22 - wciąż to samo.

Co mogę zrobić, aby przyspieszyć pgAdmin?

Pamiętaj, że psql działa dobrze, nie widzę tam takich samych opóźnień.

Czy zawsze się zawiesza?
— dezso,
@dezso za każdym razem, gdy naciskam F5, aby ponownie uruchomić zapytanie. czy wystarczy „zawsze”?

Wyciąg z pgadmin.logpokazuje, że dla każdej wyjściowej kolumny wyniku pgadminwykonuje dwa zapytania do katalogu, jedno w celu uzyskania sformatowanej nazwy typu z oiddrugiego, w celu uzyskania potencjalnego typu podstawowego.

W twoim wyciągu, jeśli dobrze liczę, łączna liczba takich zapytań wydaje się być 106.

Od czasu pingowania 148 mszałóżmy, że minimalny czas podróży w obie strony na serwer to 148 ms. Zatem minimalny czas zajęty przez ten zestaw zapytań wynosiłby 148 x 106 = 15688 mslub15.6 s

Z drugiej strony psqlklient wiersza poleceń nie wykonuje żadnego z tych zapytań, więc można oczekiwać, że zakończy się co najmniej 15.6kilka sekund przed pgadminem.

Nie znam żadnej opcji w pgadmin, aby to wyłączyć, możesz poprosić programistów lub sprawdzić, czy masz najnowszą wersję, ale pytanie podobne do twojego zostało zadane w zeszłym roku na liście mailingowej i najwyraźniej nie otrzymało odpowiedź:

Renderowanie wyników długich zapytań (w archiwum pgadmin-support).

Jest to rozczarowujący szczegół implementacji w pgAdmin. Może uzyskać wszystkie wyniki za pomocą pojedynczego zapytania, z listą typów identyfikatorów OID przekazywanych w IN(...)konstrukcji lub tablicy. Może również buforować te wyniki, a nawet nie powtarzać zapytań o identyfikatory OID, które już widział.
