Parallel Processing:
By breaking up large data sets into smaller chunks and processing them simultaneously, you can reduce the time it takes to complete a package. This can be achieved by using parallel tasks, parallel data flows, and parallelism in source and destination.
·
Use appropriate buffer sizes:
Buffers are used to hold data as it is passed between tasks in an SSIS package. By default, the buffer size is set to 10,000 rows. However, if the data set is larger or contains large data fields, it may be necessary to increase the buffer size. This can be done by adjusting the “DefaultBufferMaxRows” and “DefaultBufferSize” properties in the package.
·
Use appropriate data types:
When data types are mismatched or incorrect, data conversions must occur, which can slow down processing. It is important to ensure that the data types used in the package match the data types in the source and destination.
·
Use logging and error handling:
Logging and error handling can help troubleshoot issues and identify areas for optimization. By logging package events, you can track package execution and identify bottlenecks. Error handling can help identify and handle errors as they occur, reducing the need for re-execution and saving time.
B Nicole Snipes
When it comes to optimizing an SSIS package there are several things that you can do to optimize a package. Some of the ways that you can optimize a package of SSIS is you can default the buffer max rows which is usually set at 10,000, so you would want to set it higher due to now we have more power in our machine if not the query will sit idle so set it to like 50,000. Then another option would be to default buffer size which is usually at 10MB to about 50MB or so due to 10 once again being too small a number now. You can also write a query with statements and include what type of filtering and grouping you want instead of using a dropdown box. Then another option that would help with optimization would be to only select the columns that you need to run your query, which will help the query run faster and take less time (Verbeeck, 2023).

. Connection Managers-
One of the critical performance optimization techniques for SSIS packages is to use Connection Managers. Connection Managers store the connection information for various data sources, and using them can reduce the overhead of repeatedly establishing connections. By using Connection Managers, you can eliminate the need to create a new connection for each data flow component (Verbeeck, n.d.).
2. Buffer Size Optimization-
The default buffer size for SSIS packages is 10,000 rows. This can be increased or decreased based on the size of the data being processed. When handling large amounts of data, increasing the buffer size can improve performance by reducing the times data must be read or written to disk (Verbeeck, n.d.).
3. Parallelism
SSIS allows for parallel processing, meaning data flows can be processed simultaneously. Parallelism is an excellent technique to optimize performance because it enables the package to use multi-core CPUs. You can dramatically reduce the processing time by breaking the processing into smaller tasks that can be executed simultaneously (Verbeeck, n.d.)..

For both a speech and a written paper, the effectiveness of both comes from the person delivering whatever format because experience is everything when you compare when someone who has just started out to five years of experience. They both utilize the who, what, where, when, and why but speech can bring life to your paper, giving more depth to the words by adding your expressions. The downside to speeches is the consistency between delivery and the response from the audience, as for a written paper it is always constant when a reader absorbs the information. The textbook talked about utilizing humor in your speech to assist the audience in remembering and how to use it to make a point but also not to go overboard depending on the audience (Beebe et al., 2022). This not only can help them remember you and your speech but also help you relax if speech giving still gives you anxiety, like me.

Presenting information in a speech has advantages and disadvantages compared to a written paper. One advantage of a speech is that it can be more engaging and persuasive than a written paper. A skilled speaker can use tone, body language, and vocal inflection to emphasize key points and convey emotion, capturing the audience’s attention and making the information more memorable (Izar et al., 2020). Additionally, a speech allows for interaction between the speaker and audience, such as question-and-answer sessions, which can clarify points and address concerns. However, presenting information in a speech can also have drawbacks. One disadvantage is that a speech is a one-time event, meaning the audience only has one chance to hear the information.
In contrast, a written paper can be read and reread multiple times, allowing the reader to review and analyze the information at their own pace (Izar et al., 2020). Furthermore, a written paper can be more precise and structured, with footnotes and citations to support claims and arguments. In conclusion, presenting information in a speech and a written paper has advantages and disadvantages, and the decision of which to use depends on the purpose and audience of the information.

There are multiple advantages to presenting a speech, including it saves time, getting the audience’s attention, motivating and controlling, and having a good relationship (October 2022). It saves time because when you speak to your audience it is a quick way to talk to your audience. It helps to get the audience’s attention when you talk to them, and you can see how your speech is (October 2022). It helps you keep control of your tone and to stay focused. Some of the disadvantages are that you do not have something to look back on for further references, the reader can be confused because they cannot read their paper, and if you have a huge crowd, it will be hard due to the sound system (October 2022). The advantage of written communication is that you can have a record, and send a verbal message, and it is more reliable (Bright, 2015). The disadvantage of written communication is that it takes a lot of time.
