We have a php website running a simple simplepie installation that gathers (and cache) 5 feeds form different blogs on the same server.
We recently moved servers and the new server loads this site very slowly when the feeds aren't cached.
We assume the problem is related to caching and/or Apache settings.
We need a sysadmin+php expert to check and quickly resolve the problem.
You'll have SFTP access to the server, and WEBMIN access to apache httpd.conf.
If necessary, shell access *might* be available.
Work should be done with minimum downtime, preferably during 10pm - 4pm GMT
Please state your sysadmin/php experience in bids.
