speed up firefox

saw this on my board and i tried it out. you can really tell a difference in the loading speed of firefox! not sure what the drawback is. if you do, please share.

1.Type “about:config” into the address bar and hit return. Scroll down and look for the following entries:

network.http.pipelining
network.http.proxy.pipelining
network.http.pipelining.maxrequests

Normally the browser will make one request to a web page at a time. When you enable pipelining it will make several at once, which really speeds up page loading.

2. Alter the entries as follows:
Set “network.http.pipelining” to “true”
Set “network.http.proxy.pipelining” to “true”
Set “network.http.pipelining.maxrequests” to some number like 30. This means it will make 30 requests at once.

3. Lastly right-click anywhere and select New-> Integer. Name it “nglayout.initialpaint.delay” and set its value to “0″. This value is the amount of time the browser waits before it acts on information it receives.

quickly fill an array

i’ve been wondering what’s the quickest way to fill an array with a constant value? sometimes the code is necessary. for example, i have X number of items in an array and i wish to put them evenly into an table. to call another function, i need to pass in an array of values and an array of table width. well in my case, i just need to fill an array for table width with something like

$table_width = array('50%', '50%');

here’s my code to fill an array assuming $num_cols contains the number X.

$dummy = range(0, $num_cols - 1); 
foreach($dummy as $val) { 
  $width_per[$val] = round(100/$num_cols)."%"; 
}

Is there a faster way to do this?
