Slow, Slow Processing Website
Feb 28^th, 2008, 5:06pm

I've received a report that this site (Processing.org) is prohibitively slow in the Netherlands and I'm wondering if the same is true elsewhere. I was told that it was so slow actually, that the students weren't able to use the forum because it can take minutes to load a page. (So, if people are having severe problems, they are probably not going to get this message.)

The site is fine for me in LA (I live close to the server I think), but I want to know if we need to take action to mirror, upgrade, or move.

Please let me know.

Casey

I've never seen the website this fast before, and I've been visiting the site for about a year now. Lets hope it stays this way :) edit: I'm saying this because I'm the one who complained to Casey ;)

It's really odd. Sometimes the website is way too slow and you can hardly load a page and sometimes it's totally normal (like now).

Though the 'normal mode' has only started turning up around the time I contacted Casey, a few days ago.

My traceroute atm (while the site is fast), from Arnhem, the Netherlands:

I'll add a traceroute later when the site goes slow again.

Hi,

this happens to me too, but just from home, not from work, so i did two traceroutes and found that it is almost the same delay. What i have done now is capture the traffic when accessing the site using a network sniffer, and i have found that network speed is ok, problem is with the web server. I have found that between sending the HTTP request and receiving the answer there is a 20 seconds delay, for every request, TCP ACK is normal though. I guess this is related to some timeout in the web server, because it's exactly 20 seconds (+ delay), and my bet that this is related to reverse DNS lookups ...

Hope this helps

Btw, i'm connecting from barcelona / spain ...

When downloading files, speed is constant at about 280Kb/s.

And here is a screenshot (from today) of what i was telling in the other post http://img201.imageshack.us/img201/4051/processingca2.png

Packets 1-3 are TCP connection establishment, packet 4 is the HTTP request, packet 5 is the TCP acknowledgment from the server that it has received this data, and till here everything is fine, all of this has happened in 0.4 seconds, but then there are 20 seconds till it receives the HTTP response. From this trace it seems that network is ok, but that is the server that slows it all.
