This site is so slow.......

[tubut]

I believe resolution to the problem would require a complete redesign of AlfaBB (in such a way that there would be less HTTP GET requests per page).

Ruedi,

Do you have a listing of how many GETs we currently are at per page?

This is one of the reasons some forums don't allow things like avatars and images in signatures.

I really think the root of the cause is the advertisers scripts that are getting stuck trying to figure out what to serve for that region.

I'll need a few volunteers from the UK. I'll build some pages that have ZERO ads and we can see if speeds improve. Anyone willing to try?

Although in North America, I'll be happy to try test pages and capture traces for comparison.

For what it's worth dept: I often connect to the bb over my school's TI supported network. Usually, I do this when the network is busiest, i.e., mornings between 8AM and 11PM (when faculty members are actually in their offices! ), My connect time and download times, even with a busy network, are little different from my times using my home HS cable connection---a few seconds +/- either way---but fast enough that I don't notice a lag.

Forgot to mention this: Significantly, my connect/download times for European/UK sites (Alfaholics/others) seem to be as fast from this end as connecting to the bb in California.

I'm including the logs below for those of you who can better analize it. I can also include the logs from running it through my 3G account if you want. Just as a note every 304/407 request takes about 1sec (thumbs.ebaystatic.com also load after the page is displayed): I just tested on 3G, clicking to this page from the main page takes 15second. Refreshing the page takes 60 second

Unfortunately, the softeare does not give very detailed results (exact time stamps and what ports were used). Still, your traces contain some interesting information: Access from the corporate network shows multiple instances of "407 Proxy Access Denied." This response should not be there and indicates a problem. Every time this happens, the browser’s attempt to connect to a server failed, resulting in a retry. The first 3 rows of the "Reload - Corporate" trace are a good example. The browser tried to access the AlfaBB page "67474-site-so-slow-5.html." The first two attempts to access fail but the 3rd attempt succeeds. You’ll see this pattern repeated for several pages. Obviously, the additional requests consume time. The function of a proxy server is explained here. One possibility is that there is a problem with the proxy server capacity or configuration, but there is also the chance that the additional time the proxy server needs to cache and process the requests and responses may lead to time-out conditions. The 3G network shows no "407 Proxy Access Denied" responses. I’m guessing the reason this connection is slow is probably some bandwidth constraints.

One thing that occurred to me, do you primarily use the BB in an area where people are using internet apps, (such as webmail)? I've found that these suck up so much bandwidth, it makes sites such as the BB almost unusably slow.

[brookstroutr]

Well, I've only perused the posts on this issue and the reason is it's slower than stink! I'm on a few other forums and none are as bad, speedwise, as this one. That's my only constructive comment as otherwise I reeeeally like the site and format. However, sometimes it's sooooooooooo sloooooow I drift off to another site (AlfaGTV6.com, etc.).
