Hi,

i testing the latest release of pgadmin4 (rc1) and noticed that the query tool is significantly slower than the query tool in pgadmin3.
i am not sure if this occurs only on my computer or only under os x (10.10.5) or is this a known behavior.

I don't know. You might get an answer quicker at the link below though:

how to repeat:
create table test1 (a int, t text);
insert into test1 (select generate_series(0,25000,1),'Lorem ipsum');

create table test2 (a int, t text);
insert into test2 (select generate_series(0,25000,1),'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent sit amet auctor lectus. Nulla condimentum maximus mauris, ac mattis leo blandit eget.');


select * from test1;
pgadmin3: Total query runtime: 518 msec
25001 rows retrieved.

pgadmin4 1.0 rc1:
Total query runtime: 2 secs.
25001 rows retrieved.



select * from test2;
pgadmin3:
Total query runtime: 2.8 secs
25001 rows retrieved

pgadmin4 1.0 rc1:
Total query runtime: 14 secs.
25001 rows retrieved.

client: os x 10.10.5
server: debian jessie in vmware, pg9.6-rc1

thanks,

Attila
