| Summary | 0004387: bugs.scribus.net and wiki.scribus.net: Long response times | ||||
| Description | Bug tracker and Wiki: we have had very long webserver response times for a longer period of time by now. It's definitely something to be looked on and tweaked by the webserver administrator. Tested with Firefox (long responce times) on both Linux and Win32 platforms and with IE 6.* (desastrous responce times) | ||||

|
Response is immediate for me. |
|
|
Current (meaning now) response times for the Wiki Main Page http://wiki.scribus.net/index.php/Main_Page, measured in my office in Vienna, 2 MBit downstream: IE 6.*: ~ 90 sec Firefox 1.5.0.7: ~ 20 sec For http://bugs.scribus.net/my_view_page.php : IE 6.*: ~ 40 sec Firefox 1.5.0.7: ~ 4 sec |
|
|
Measured somewhere in Australia: "Takes around 9-10 seconds here to load wiki thi scribus icon in rh corner seems to be the last object? to load on Linux using FireFox. A little bit slower using konqueror catchya Dean" |
|
|
Tested at home on Linux and http://wiki.scribus.net/index.php/Main_Page - Firefox 1.5.0.7: ~ 17 sec - Konqueror 3.5.3: ~ 4 sec |
|
|
Tested from a small town in France: http://wiki.scribus.net/index.php/Main_Page : IE6: immediate Firefox 1.5.0.7: immediate http://bugs.scribus.net/my_view_page.php IE6: 0000036:0000010 sec Firefox 1.5.0.7: 0000011:0000003 sec |
|
|
Tested from Germany, SuSE Linux 10.1: Konqueror: 4 seconds SeaMonkey 1.0.5: Forever, more than 20 seconds Using a DSL connection. I have also been wondering why the Scribus sites have become extremely slow recently, esp. in Mozilla/Firefox/SeaMonkey. |
|
|
Seems Ok here on 8Mb DSL with FF, seamonkey and Konqui Suse 10.1 |
|
|
Some recent updates made by Peter are also gone since the last server downtime. See e.g. http://docs.scribus.net/index.php?lang=en&page=install1 |
|
|
I have a hunch what the problem might be. Can someone please confirm that it is working fine right now? Once I get that confirmation, I'll apply the change I'm planning. |
|
|
ltning: Yes, I can confirm, it's radically better now:) Measured from my office in Vienna: http://wiki.scribus.net/index.php/Main_Page IE 6.*: ~ 4 sec Firefox 1.5.0.7: ~ 4 sec http://bugs.scribus.net/my_view_page.php IE 6.*: ~ 4 sec Firefox 1.5.0.7: ~ 4 sec Just out of curiosity: What was it? |
|
|
The problem seems to be PF-related. I am using PF (packet filter, originally from OpenBSD, now also standard firewall in FreeBSD) to redirect incoming traffic to a transparent proxy server. As the proxy server in question is used at some of the busiest (including *the* busiest), I looked at PF to find the problem. The current theory is that I have a problem with packet reordering. As PF redirects from/to the same IP address, there could theoretically be a problem with TCP sequence numbers when re-using a connection. I will try to work around this by having the proxy server listen on a different IP address, thereby making the sequence numbers irrelevant to packet identification. Anyone with hints or tips around this are welcome to get in touch with me ;) |
|
|
ltning: I'm so happy with the current speed (what a feeling! Working with Scribus Wiki is fun again:), that I simply have to ask, if you just couldn't leave it the way it is now -- I assume, you pass the incoming traffic directly to the webserver machine. <quote>I am using PF (packet filter, originally from OpenBSD, now also standard firewall in FreeBSD) to redirect incoming traffic to a transparent proxy server. As the proxy server in question is used at some of the busiest (including *the* busiest)</quote> I don't have any experience with proxies (only with our Cisco Pix firewall), but what exactly would be the advantage of redirecting _incoming_ traffic to a transparent proxy? No irony, it's a serious question, since I've just read that transparent proxies were useful for outcoming requests for obvious reasons (no need to manually add proxies in client configuration, less traffic). |
|
|
By having that proxy there I'm cutting server load by >50%. The alternative is to have someone buy me more hardware.... ;) Good enough reason to use it, if I can make it work right? Btw: If the problem is what I suspect, it's actually your PC/router/whatever that is causing the problem by re-using an outgoing port number for a new connection before 90 seconds or so has passed. This violates the TCP RFC. Just FYI ;) |

<quote>Btw: If the problem is what I suspect, it's actually your PC/router/whatever that is causing the problem by re-using an outgoing port number for a new connection before 90 seconds or so has passed. This violates the TCP RFC. Just FYI ;)</quote> ltning: just to make clear what's about: my "PC/router/whatever" is a number of PC's (over 20), connecting to the internet through a Cisco PIX 506E firewall and a Cisco router, no proxies, no DMZ or such stuff -- I've observed the behaviour over a longer period of time. Then there is my PC at home: pretty much the same, a stock Linksys router between me and the internet. Then there are some other users over the world which encounter the issue, e.g. see the c_schaefer's report above. Or there was a user, for whom I'd created a wiki account, who reported the following: "Thanks; I have successfully logged on and started editing. Can you tell me why the page loading is so slow? It takes about a minute to load the Wiki preview, for example." |
|
|
<quote>The alternative is to have someone buy me more hardware.... ;)</quote> Just an additional idea: what kind of hardware at what estimated cost would it be? If you deliver your IBAN/SWIFT or PAY PAL account number (soon:), we could place a request for donations on the wiki main page, and post to the mailing list. I would gladly donate a few euros myself. |

I agree, the problem I describe seems highly unlikely to be the cause. I'll do some further digging. It could also be a timing issue. Do you have a special MTU setting on your connection? Using PPPoE or something? As for hardware, I'm doing some upgrades today (more memory, disk). Some on the Scribus team has already donated some to that end, others are of course welcome to do so, though it hasn't been widely announced. I believe there's some work going on to set up a non-profit organization that can collect donations directly, and distribute where needed - which is a much cleaner approach. Of course if you wish to donate to the hosting specifically, you're most welcome to. There is info about that on some of the scribus pages (wiki?). |

<quote>Of course if you wish to donate to the hosting specifically, you're most welcome to. There is info about that on some of the scribus pages (wiki?).</quote> There is no such info about it on any of the scribus pages (we've been asking Scribus team for years now to provide such info:), that's why I'd suggested that you provide your IBAN/SWIFT or PAYPAL account number and the roughly estimated price of the hardware -- I would put this info on the wiki page then, with a short description, why this donation is needed. |
|
|
You can use http://anduin.net/donate.php for cc donations, or paypal to ltning@anduin.net . |
|
|
We are still awaiting the creation of the not-for-profit org in France. The forms are in and we await the publication. The day after that, I expect we will have an account. |
|
|
Just to be sure: what do I need do to use the "CC donation" form? Is this "CC account" something I can get from this page: http://donorge.org/ ? Also, as mentioned before, I would like to know to what kind of hardware at what price I'm going to donate for. |
|
|
Sorry, by cc i meant credit card. As for which hardware, the initial need is for more memory and hard drive space. I have added more of both today, next up is a dedicated RAID controller (using software RAID today, which is a performance bottleneck), for which i also need a riser card. |

ltning, thx, I've just sent you a small donation with paypal and placed a request for donations on the Wiki: http://wiki.scribus.net/index.php/Scribus_Public_Wiki:Site_support cbradney: bad news:) I've just learned that to be able to receive a paypal donation you don't even have to have a paypal account, an e-mail address is sufficient. This means, our eager mailing list donators could pick their favourite Scribus team member and donate to him personally, until you'll be able to receive donations for your non-profit organisation. |
|
|
I'm not sure how to get money via email tho :).. In any case, we have resisted taking personal donations generally unless we have really been in need, hence the org requirement. |
|
|
mhanski, haven't seen anything from paypal at this end.. Mail me if you have any questions. Thanks for your support! ;) |
|
|
<quote>I'm not sure how to get money via email tho :)..</quote> :) That would be just email money, I guesss:) Speaking seriously, you would be notified by PayPal about the donation and would have to create a PayPal account to pick the donation up. |
|
|
ltning, sorry, this time I managed to click the second "send money" button, I'd missed the first time:) (Transaction code: 9W62591445618484C - this was my first experience with paypal). |
|
|
Can we close this now? |
|
|
Nah, I'd prefer to keep it open until I've finished investigating. I need to be able to use PF (it's an absolute must), and I need to use a proxy to get the load down to a sensible level. Just need to find the time. |
|
|
I think, this one is ripe to be closed now |
