Want to make pages load in a blink.
My front page takes 1.1 s to load with ping 74 ms. A similar (ping 72 ms) English wikipedia page (actually 40% larger document on a heavily used host) loads in 0.4 s. My site runs Mediawiki software under APC on a dedicated host with 1 GHz Athlon, there barely is any traffic and the machine has some free core memory.
Is there a way to speed up the load, or anything I could look at? I've tried squid and there was no improvement at all.
The test I used was
time wget url
P.S. I've asked similar question, but I think it was not stated clearly enough.
