Re: High I/O writes activity on disks causing images on browser to lag and not load

I don't understand what kind of research you want me to do. I don't have any performance problem other than that images seems to get stuck on occasion, with a certain amount of users.This is what I've got, and I have spent several weeks reaching this stage. I started by removing a router and arranging another internet, benchmarking the application, study the network card, switching to Apache Server and I have ruled all of them out. I have now come to the disk, and here its postgre thats most active and its starting to feel right, but I could be wrong but what other leads do I have?

Since even a select count(*) outside my application is causing this I do not understand what conclusion I should take. After all, you said it yourself, you do not get any writes, why do I ? With perfmon under heavy load I registered 4000 I/0 transefers / sec and they where all writes so I think I am getting closer.

Here is a similar one but on linux

I am will try turn the stats off, but I am not sure how that might affect the db's internal stats on how to best run a query, what indices is good or not.. ?
