I've upgraded to XOOPS 2.2 and have all my modules also upgraded smoothly. But unfortunately something happend in the final process.

I have orginally near 100 blocks. Due to the change of blocksadmin, I have to add a lots of blocks back to my site. It goes without problem in the beginning of adding blocks. But the more blocks that I add, the harder the blocksadmin page loads after adding a block. When there's over 60 blocks in the blocksadmin pages, it finally stops loading in the half way. Even that I reload the page, only the admin menu appears. About 1 in 10 times, the whole page shows but very slowly. (I've also tried blocksadmin 1.2 module but the same result.)

This is never happened in XOOPS 2.0 when all the blocks were not showing in one page. It's a bit painful to use 2.2 blocksadmin for a site having many blocks. Besides some modules like CBB that have individual blocksadmin access, I hope there's a way that I can add the rest of my blocks back.

In spite of this problem, XOOPS 2.2 runs perfectly for my site up to now.

If you mean the problem is all the blocks doubled after modules updating, I think it is not only for webmasters but all users.

If you are using 2.09, you can track this post

Trying to make a better perfomance of my website and considering both sever loading (to admin) and browsing speed + convinence (to user). I'm getting confused with the setting of session function and autologin hack.

How to make a optimized setting to improve site accessing and browsing speed without increase server loading too much? Will the autologin hack eat a lot of resource if there're always many online users entering with it? If sever loading is the main concern, should I keep any of them?

Any suggestion will be appreciated.

Thanks you guys for your help, here's more information.

I never thought of deleting member accounts until my hosting provider told me that I currently have used over 1/4 of the servers processing power. Besides, my site was suspended a few times when suddenly too many users were online at a time(I guess it was around 50-60 users when my site had higher traffic in the holiday nights, but this not usually happened).

Indeed, my site is not particularly popular. Also the bandwidth and other stats seem OK so far. So the large registered users(even a little higher than forum posts) is something might take notice for. I understand there's many possible reasons that also relate to site proformance and I have been trying many methods and optimization to reduce the server loading(Cache function have enabled for most of the modules and blocks except the forum and its blocks). But most of the jobs seem like don't help much.

As Stewdio suggested, I've just turned off a stats modules and am thinking how to make my site more simple. Hope it can make some difference. However, for the user accounts issue, I'm just curious about how many occasions or how often does XOOPS connecting to user database, and wonder if a large user database will serverely reduce server performance than other factors.

There're over 16,000 members of my site. The registered users are increasing day by day while the average daily vistors are remain stable for most of the time .

Recently, it seems like it's getting slower to browse my site and it always overloads the server. I wonder it is mainly because of the increasing registered users since the average site bandwidth and online users have stayed in the same scale(not increased).

I'm not exactly knowing whether increasing users will also increase lots sql inquiries or too many users will cuase a database problem. But if there's a possibility to decrease the server loading, I'll consider to delete some users that haven't login for a long time.

I am in a shared server, bandwidth is about 20gb/m. 20 users online in average.
