You can block "bad" spiders and bots quite easily, using this mod.In addition you should change the usergroup permissions, setting limits on signature images. For future.

Are you serving them from your file system or the database?

Don't use gtmetrix for objective testing - they are trying to sell you optimization services. Use WebPageTest only. It is real world, objective and not trying to sell you anything.

I re-test you, same thread and same test parameters, and you're down to just under 5 megabytes now. There still exist several massive animated GIF images in signatures. There is only a tiny bit of improvement here.

many users had been remove their gif signatures .. the current cpu status is 33%


Usergroup permissions.

These are signature images that are being served third party, there is no way for him to control them or move them. He just has to LIMIT them. Nobody needs a 4 megabyte signature image.

yes but that is not the cause of his high cpu usage or mysql load. :)

Yeah I'm just trying to get the pageload down out of the 8 megabyte crazy tree so we can see what is going on with showthread.php - which is the page his host says is causing all the server load.Why don't you just take a look at them and scroll through them, options exist there for limiting signature images, avatars, uploads, everything.
