First query takes 4+ minutes to complete

Hi, we are evaluating ObjectDB 2.5.1_04 in embedded mode hoping to replace SQLite in our application.

Can't post on your forum

Since yesterday, I can't post on the forum because it always says that I should log in in order to do that. I was already logged in, but, anyway, it appeared as not. I go to log in, then I authenticate, then I'm redirected to the home page, but it still looks that I'm not logged in, so I can't post on the forum. I tried removing the cookies, but nothing. I tried in another browser, but the same. I have new bugs to post, so it's pretty important. ... to moving our website to a new host, and maybe some cache issue.    ObjectDB Support ...
