hi
when I've installed the server it was checked the option to copy client library to system folder


in FB 3
select * from MYTABLE where id=200 
takes 6 seconds


select rdb$get_context('SYSTEM','ENGINE_VERSION') from rdb$database

result: 3.0.2

for  'select * from Mon$Attachments' iused flamerobin to export result as csv:

MON$ATTACHMENT_ID;MON$SERVER_PID;MON$STATE;MON$ATTACHMENT_NAME;MON$USER;MON$ROLE;MON$REMOTE_PROTOCOL;MON$REMOTE_ADDRESS;MON$REMOTE_PID;MON$CHARACTER_SET_ID;MON$TIMESTAMP;MON$GARBAGE_COLLECTION;MON$REMOTE_PROCESS;MON$STAT_ID;MON$CLIENT_VERSION;MON$REMOTE_VERSION;MON$REMOTE_HOST;MON$REMOTE_OS_USER;MON$AUTH_METHOD;MON$SYSTEM_FLAG

And did you update client library as well?

please run this sql in isql and post here result:

select * from Mon$Attachments

and for sure

select rdb$get_context('SYSTEM','ENGINE_VERSION') from rdb$database
