Check for Memory Leaks in your SharePoint API Code

-

 

Microsoft has just released a memory leak checker for SharePoint code. Not sure if all your SPWeb and SPSite objects have been properly disposed? Use this tool to discover which lines of your code are not properly disposing of those objects.

 

Each SPWeb and SPSite object takes 1-2 megs of unmanaged memory. So no properly disposing of them causes major memory leaks. However, (this is important) if you dispose of a SPSite object that you get from SPContext.Current, you will crash your SharePoint site. So having a tool that you can run to definitively determine if your production code is good, is a big help.

RAM Disks do not speed up Visual Studio

-
  The limiting factor for Visual Studio is disk IO. I got a tip to speed up Visual Studio from Channel 9 by creating a RAM disk which sounded like a great idea. However, when I ran a thorough set of tests, I found that the performance difference between the Ram disk and the hard disk were not appreciably different. This was a big surprise since RAM is 240,000 times faster than disk (see my previous blog post). But the reason is because Visual Studio and Vista do a lot of caching. So compile times for the same project in RAM disk and on hard disk were pretty similar. I also tested the time it took to search the entire solution for a word, and times to open a solution. There was no discernable difference!   If you still want to try it out and create your own RAM disk, you can download a simple RAMDISK.EXE utility to create a RAM disk in just a few minutes. What is a RAM Disk ?   Ramdisk is a virtual drive created in RAM.   Performance Analysis Creating files was an average

Tableau Bridge is now availble on Linux Containers. Yay! Now what does this mean and how do I build and run Linux Containers? We will discuss the advantages of running Bridge on Linux Containers the steps to build them, and finally, we will provide some automation script ideas for monitoring and scaling Linux Bridge agents. Tableau Bridge Today Until recently, Tableau Bridge was only available as a Windows application running on a Windows VM. It supported only one bridge agent per Virtual or Physical Machine. Advantages of Bridge in Containers Better Hardware Utilization: Linux containers are more efficient than Windows VMs, requiring only about 1/50th of the disk space. Ability to Spin Up Multiple Bridge Agents: With Linux Containers, it becomes easier to spin up multiple bridge agents on a single machine, improving scalability and resource utilization. Infrastructure Automation: Linux Containers enable easier automation of provisioning bridge agents and upgrading Tableau Bridge, the
