2012-01-03 05:06:32 - Poor responses from the server?
Hi guys!!

Anyone else having a problem getting a response from the server. My access is poor and it only happens when in the SOL site. Getting into the home page is OK but thereafter the responses are slow if at all. Add to this the fact that when I do get in I have to upload my commands a number of times before the server responds with the action.

This is the error I get when trying to get into the race page.

"Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data"

Regards
George

Hi George,

I have no problems at my end atm, and had a good look at the server logs, nothing strange there either. I will keep a close watch on perf and response times.

Did you have this with a specific race or more then one?

Hi Jeroen!!

I only noticed it during leg 2. I'm off to Harare in Zimbabwe on Sunday and will be able to check the response from the service provider from there as a cross check. If it is good then when I get back I will purchase a second data modem and sim card from the opposition. Brother, boat Henrys, down in the Cape says that Vodacom data service in Velddrif is better than MTN. So we shall see.

To be honest. Only when I get back from Zimbabwe will I be able to sail short and fast races and it is then that I will require my uploads to be 100% responsive, one of the secrets to my short race good results is "pinching" plus a few other full time adjustments tricks!!!

Lastly. Jeroen, Im going to see if I can download a different web browser when in Zim to see if it is Google Chrome giving me the problems.

Thanks for the response.

George

Have things improved for you Jawz?

I would doubt it is Chrome slowing things down, indeed I prefer Chrome especially for SOLing precisely because it is faster (and automatically updates Flash for you)

I also used a 3G modem for many months and usually had no problems speed-wise, but certainly there were times when it would switch away from a 3G network to HSDPA or HSUPA. The former still provides fast downloads, but the later can be a bit slower.
HSDPA = High Speed Download Packet Access
HSUPA = High Speed Upload Packet Access

I could see in my modem software which type of network it was currently connected to. Another situation that can slow things down is if it is 'jumping' between network types quite frequently.

Also it is possible you have a dodgy SIM card. Your provider should replace it free of charge - or possibly the modem is faulty, which they should also replace for free if indeed this is that is the case.

Was (is?) it only SOL you notice speed drops with, or other websites to (like the VOR live stream and the like, not Google)

Also, if you could be more specific about what you mean by 'response from the server' it would be helpful. Did the client or wx take longer to download? Commands you sent take longer to turn up in the client? DC list refreshes? etc
Perhaps uneven time intervals between boat updates - some taking the usual 15 seconds while others may take longer?
I help develop the client interface for the best online ocean racing sim there is... __/)/)_/)__

Hi Aaron!!

Sorry for the late post, I am up in Harare, Zimbabwe and work got in the way! To answer your queries now would be too soon because I want to check things out when I'm back home in SA.

What I can say is that I have loaded Firefox and all my symptoms appear to have gone. This will be proven when Leg 3 of the World race starts on Saturday and I will check to see if I'm ok from my temporary office during weekdays because weekends are dodgy with poor network coverage at "home". What I was experiencing, only on SOL,and it appears only with Chrome, was
1) a difficulty in getting into the various pages from the home page
2) a difficulty in loading the race page. Sometimes I get the map, then not. Sometimes I get no weather. Sometimes no boat info
3) when eventually I manage to load the race page then my commands had to be entered a few times before being accepted by the sol server.
4) comments on race page chat would not be uploaded

As I said, I will do a comparison between browsers when I get home so we will take up the challenge again in two months time!

Thanks

George

Transat à Deux 2025

Above you see a single-handed sailor semi-foiling his Beneteau Figaro III to the horizon. It is in fact Ireland’s Sailor of the Year and the overall winner of last year’s Solitaire du Figaro, Tom Dolan. Somehow, we got our hands on a polar for the Class, and rather than trying to surreptitiously track Tom and his mates in the 2025 edition of the Solitaire, sailing rather-short, single-handed legs across the Celtic Sea and Biscay, we thought we’d see how our virtual craft would fare on the Class’s double-handed 3900nm Trans-Atlantic, from somewhere in Brittanny to somewhere in the Caribbean via somewhere in the Canaries. Allez, mes braves!

Sinbad by Balloon 2025 - Toamasina to Baia de l'Oiseau


You may recall that when last we visited Madagascar in the company of Sinbad, the Sultan commanded our intrepid inspirator to seek out fabled islands where in Summer the sun barely set. We did and we returned but the Sultan wasn’t happy with Sinbad’s report, so here we go again, now by SOL Balloon instead of sailing vessel. Expect to be in the air for at least 2100nm and depending on how the wind brings us, anything between two weeks and two months before we shall descend at the Sultan’s given coordinates!

Melbourne Osaka Cup Double-Handed Yacht Race 2025

Welcome once again to what these days is Sailonline’s almost annual virtual Melbourne to Osaka Yacht Race. In real life, this double-handed 5500 nm race between these two sister cities, one deep in the southern hemisphere, the other high in the northern hemisphere, is run every four to five years, and this year is such a year. So, this year’s online version is in sync with the Melbourne Osaka Cup 2025 organised by the Ocean Racing Club of Victoria (ORCV), and the Sandringham (SYC) and Osaka Hokko (OHYC) yacht clubs. We’ll be racing the well-known First 40, a popular size of boat which should be a good match for many of the boats entered in the real race. With the doldrums unavoidably lying across our course, you can expect to be at virtual sea for at least a month!
