Performance Issue

Hi Israel,

We regret for the delayed response.

We are currently working on optimizing the performance for Schedule Control. The fix for this issue will be available on or before September 15, 2009.

Please let me know if you have any concerns.

Thanks,
Melba

Hi Melba Winshia,

Is the performance issue resolved in the Schedule Control version 7.3.0.20? You said it should be by 15Sep09.

We are facing serious performance issue in version 7.1.0.30 in production for a project which has gone live into 3rd week now.

Need your confirmation before we upgrade the control for this live project.

Thanks,
Joseph Yong
Project Manager

Hi Joseph,

Thank you for your interest in Syncfusion Products.

I am able to see performance issue with version 7.1.0.30 while loading more number of appointments. But we are glad to let you know that we have optimized performance while more number of appointments is loaded and the fix for this issue is available in the Development build v7.4.0.9 which you can refer to the below location for download.

Hi Melba,

We update the version of the Schedule control on our project, to verify the results. We can notice some gain in the performance of render.

We had a scenario where was delaying around 17 seconds to render the Schedule control. After this update, this time was reduced to 8/9 seconds. As you can see, the gain was significant, but from user point of view, this delay is inacceptable.

We are using Linq To SQL to bind it. Resources and BlockedTimes are being created at runtime. The site is hosted on Windows Server 2008 R2 with SQL Express 2008. The server-side code is running fast. The problem/delay is the render in the browser. We are using Internet Explorer 8.0, and we had tested many of browsers and versions, like FireFox, Opera, Chrome, etc., and all of them have the same problem/delay.

Can you help me to diagnostic this problem? Below I paste my control markup (ASPX) to you view it:

CategoryDataSourceID="" Height="100%" TimeMode="Hours24" UserOverrideCulture="Portuguese (Brazil)"
Width="100%" CultureSource="UserOverride" ShowPrintStripItem="False" WaitingPopupText=""
ShowDeleteStripItem="False" AllDayAppointmentRowVisible="False" AutoPostBackOnScheduleClick="True"
AllowAppointmentDrag="False" AllowAppointmentResize="False" ClientSideOnAppointmentClick="Editar(this)"
ClientSideOnScheduleClick="SelecionarData(this)" AutoPostBackOnAppointmentClick="True"
DayNavigatorPosition="HeaderLeft" ShowDayStripItem="False" ShowMonthStripItem="False"
ShowTodayStripItem="False" ShowWeekStripItem="False" ShowWorkWeekStripItem="False"
OnStartDateChanged="Schedule1_StartDateChanged" AllowAddingAppointByCallBack="False"
EnableTheming="False" HeaderBarVerticalAlign="NotSet" ShowNavigator="False" ShowNotedDaysInCalendar="False"
DayEndHour="23" ResolutionHeight="24" ShowCategoryGroupBar="False">

Hi,

I'm looking for some people that is passing for the same problem, and I found this post: http://www.syncfusion.com/support/forums/schedule-aspnet/90787/Property-DayStartHour=8-makes-loading-of-appointment-so-slow!

Just to complement the previous post, I have, in average, around 80 appointments per day, with 19 horizontal resources. You can view the attached image.

Hi Israel,

We analyzed your issue, we like to know which version you are using. In addition to that we have analyzed and found that the rendering delay is also caused due to the shadow of the appointment. To optimize that, you can set the ShowShadow property of the schedule control to False. Please find the below code snippet to use it.

runat="server" ScheduleType="Day" AutoFormat="Office2007Blue">

Please try the above and let me know if any concerns.

I have the same performance issue. It takes ages for the schedule to render, when i enter to the page or when i use the schedule context menu.
can't the context menu work on client side?

Hi,

I have tried the sample.
It takes 7 seconds for the appointments to upload..
We usualy use more then twice as much appointments so it takes 12 approx seconds (i added to your sample 20 more appointments)
This is unacceptable for our customers,
what should i do?

Regards,
Hilla

Ranjithkumar hi,

Well you are right, the prerender time almost the same for me to.
The problem is after onunload. I don't know what comes after that, but between onunload and the display of the schedule control on page, above 10 sec waisted.
