I have just installed ubuntu 12.04 server on our new DL360p Gen8 E5-2690, but it generates a lamp-site slower than my iMac running os x.
The website runs about 20 queries on a normal load, if I reload both pages they load about equally fast, ~50 ms, but on first load the iMac is sometimes twice as fast, 100 vs 200 ms.
The iMac has an ssd, the hp server has 8 1.2 TB 10rpm raid 5.
The iMac has an i7 3.5Ghz, the hp has two 2.9GHz with 8 cores.
The iMac has 24 Gb ram, the server 64 Gb.
Running the website on my iMac in ubuntu using vmware renders the page 30 % faster than when using os x.
Is this expected? Is there something I´m missing?
