    Muselive.com is backed by a MySQL database, however since our website nice recently it has been running very slowly. We think that the database is not correctly configured or optimised. We would like something to take a look at our current set up and make changes to improve performance. We are confident that no queries will need to be changed and that this is purely a config issue.

Instruction has been found here http://www.policyd.org/Need to test it before hand over to me.( Must finish in 72 hours after the login is given)Part Two:Currently emails send out of this server go to SPAM folder of gmail (I believe other email providers as well.) I have already setup reverse DNS for the IP.Need to solve this problem.******** IMPORTANT ******You need to let me know in general what you are going to do when you bid in order to prove you know how to do this project.

    We have a number of GoDaddy private servers that we need optimized for running 20+ WordPress websites that receive anywhere from 10 to 100 hits per day. As the number of websites has gone above 20, the server has started to slow down and become non-responsive at times. We need someone to have a look at the server and propose changes to it that will allow not only these 20 but more sites to be run from it without affecting performance.We have technical skills in house and we are not looking for generalistic advice. We have been working on this issue for months looking for advice on the web and implementing various optimizations. The issues we are seeing are specific to our configuration and my expectation is that the person or company selected to help us will spend some time on the server doing analysis and then providing suggestions.We are a growing company and are about to add more servers. This could be an opportunity to partner with us not only now but in the future.

    I have a problem on Shoes.co.uk which is slowing down the site load speed. We do not send mailshots from the website but there is a script running that is concatenating various mysql entries and sending something to a mailshot manager. It is consuming a huge amount of processing power that is slowing the website load to 11-14 seconds when it is normally 4 or 6. This is from Rackspace:Id User Host db Command Time State Info5144 shoes localhost shoes Query 3 NULL SELECT cat_id FROM product WHERE product_id = &quot;4297&quot; and(select 1from(select count(*),concat((select (select (select concat(0x27,0x7e,unhex(Hex(cast(mailshot_queue.mailshot_queue_email as char))),0x27,0x7e) from `shoes`.mailshot_queue limit 47966,1) ) from `information_schema`.tables limit 0,1),floor(rand(0)*2))x from `information_schema`.tables group by x)a) and &quot;1&quot;=&quot;1&quot;5143 shoes localhost shoes Query 2 NULL SELECT cat_id FROM product WHERE product_id = &quot;4297&quot; and(select 1from(select count(*),concat((select (select (select concat(0x27,0x7e,unhex(Hex(cast(mailshot_queue.mailshot_queue_email as char))),0x27,0x7e) from `shoes`.mailshot_queue limit 47965,1) ) from `information_schema`.tables limit 0,1),floor(rand(0)*2))x from `information_schema`.tables group by x)a) and &quot;1&quot;=&quot;1&quot;This happens when the CPU is peaking.

    We recently hired a server management team to secure our server. In the process issues have come up that did not exist before. Pages loading only partially, and poor results using https://www.blitz.io/. We are looking for someone who can optimize our server towards WordPress. At the moment we have 70 to 75 websites. All run a caching plugin (SuperCache mostly). Below are a few pdf files of Blitz load test reports, and screenshots of issues that are experienced when accessing the website. Also, one of the Blitz pdfs comes from 2012, when we first got the server. At the time of the test, only 2 websites were on the server, and it tested extremely well.Basically, we need our server optimized to work well with WordPress. Also, to go over &quot;setup&quot; that was created by the server managment team we hired (they focus on security).

    Hello, Recently hired a freelancer to migrate my site jooml 1.5 to 3.0. After migrating the site started having serious overload problems in MySQL&quot;s CPU usage is too high, causing a drop in site and all server resources. The CPU usage by MySql reaches to 70% at times. I can only leave a little stable server leaving the site in maintenance, otherwise it is impossible to navigationI contacted my hosting server and received the following information:Those PHP processes are caused by your site files/scripts running. The way to resolve this issue is to optimize the code, and check all the php code to make sure it is closing properly etc. This is a site development issue and is out of our scope to assist you with.Because there are so many of the php processes, they are raising the load of the server, which makes it slower to respond. This is also the reason for slowness on your websites.My site is www.valenews.com.brOlá, Recentemente contratei um freelancer para fazer a migração do meu site jooml 1.5 para 3.0. Após a migração o site começou a ter sérios problemas de sobrecarga no MySQL. O uso de CPU está muito alto, gerando uma queda no site e em todos os recursos do servidor. O uso do CPU pelo MySql chega á 70% em alguns momentos.Só consigo deixar o servidor um pouco estável deixando o site em manutenção, caso contrário fica impossivel a navegaçãoEntrei em contato com meu servidor de hospedagem e recebi a seguinte informação:Esses processos PHP são causados ​​por arquivos do seu site / execução de scripts. A maneira de resolver esse problema é otimizar o código e verificar todo o código php para ter certeza que está fechando corretamente, etc Esta é uma questão de desenvolvimento local e está fora do nosso alcance para ajudá-lo com. Porque há assim muitos dos processos de php, eles estão aumentando a carga do servidor, o que torna mais lenta a responder. Esta é também a razão para a lentidão em seus sites.
