Say if I have an array of 500 url's that I want to retrieve how do I use your function for that ? If we could I could see your jpeg example, i'm sure it would become much clearer. Many thanks in advance. Jason Hi Anton

What we had exactly is that before deployment of multi-threading solution it was approximately 1 hour and after only 2:50 minutes. I could assume that data density was ~30-40%, actually there were 4 vendors for the hardware e-shop, each had ~700-1200 products after filtering to be listed in the shop. Although every product had a link to the picture, not all the products had a picture behind this link (~60-70% had not). The request was made anyway, and actually multi-threading solution has also reduced time of checking the link. This is my assumption.

So the comparison in the end is hard to believe. Say we have 3000 JPEGs of 1 MB each. That's 3000 MB. To download this on a 8 Mbit line takes 3000M*(8 bits)/8Mbits = 3000 seconds. That's 50 minutes for downloading only, and under ideal circumstances. This does not mean multithreading isn't a speed booster, but not as much as I would be led to believe by the claim made in the last paragraph.

Do you mean "serialized PHP object"? It is like in java, you can "store objects" as text if you want to use them in some enother execution of the programm. If you serialize some object into JSON in Ajax, it is almost the same thing. Well, actually the code is complete to execute the example. Do you mean “serialized PHP object”?
