Optimizing load-balancing

I run a medium dating site 1 database server 1 nfs server 1 load balancing server 1 backup server 4 web servers (or similar, my main unix admin might have changed the configuration) There is about 20 000 unic visitors a day with an average of 300 users online all the time, making requests. My problem is that even with all those servers, the site is slow and often gets a 504 gateway timeout error. My need is someone that is vell experienced with unix/linux, php/mysql, nfs and load balancing systems, to help us optimize our system so we can reduce load, give faster responses to sql requests and mainly: eliminate lag and errors. If i gain confidence, i will be willing to give acces to the load balancer server and 1 web server for your to fix it. If it works, you will be able to tune all servers or tell my admin howto. Opportunities for long-term relationship are there also. Even if its a big site, incomes are very low considering all expanses, so please dont bid too high :) ## Deliverables 1) optimizing our load baslancing system so the site goes faster 2) tuning unix apache, php, mysql 3) documentation of everything that was done so my main admin knows exactly what is happening. Note that it might be less, or might be more I will give you a bonus if you make a great job. If you just tune a little bit, probably no bonus will be given. * * *This broadcast message was sent to all bidders on Tuesday Jul 26, 2005 12:50:36 PM: Hello, Finally, even after my main admin retuned servers, we still get lag and time out errors. If you are still interested helping in this project, please bid again. Descprition has been modified a bit.
