coolRunnings speedup

[GoogleCodeExporter]

coolRunnings is 10x slower than last week. Below are three sites I tested
with the response time for index.php. I also included the full URL. Are you
seeing similar response times? (This will help determine if it's on my end,
like my network.)

eBay.com: 40 seconds
wordpress.com: 34 seconds
www.yahoo.com: 107 seconds

Original issue reported on code.google.com by stevesou...@gmail.com on 9 Sep 2009 at 7:19

[GoogleCodeExporter]

ebay is indeed crazy, crazy slow. 

Going to try looking at a profiler for the ebay call. Hoping it's something 
simple.

The problem is the call to pngcrush. Not only is it time-intensive, the single 
ebay
call takes my server load from 0.03 to about 0.6, which is very bad.

I've disabled it for jh.com/coolrunnings, but it is still enabled for
csscoolrunnings.com. 

What do we get for our trouble? In this case, not much:

39.12 KB (40062 bytes) <-- w/pngcrush
43.78 KB (44834 bytes) <-- no pngcrush

We're taking a huge time hit for nominal file-size savings. 

Temporary fix: I'm going to disable pngcrushing at jh.com and look for 
something more
efficient. To allow comparisons, I'm going to leave it enabled at 
csscoolrunnings.com
just for today.

no pngcrush:

[GoogleCodeExporter]

Found a workable compromise.

The command that had been used at jh.com included the '-brute' call to pngcrush,
which meant pngcrush looped through 130 different algorithms instead of the 
default 10.

By simplifying the pngcrush call, response time is way improved, and server 
load is
much lower.

Putting this into production at both sites; leave a message here if it slows 
down again.

marking as fixed because it seems to be working really nicely. Reopen if it 
doesn't
seem so nice to you :-)
