# Sluggish Behavior in SEL

What to check when ENERCALC SEL feels sluggish, including updates, file storage, antivirus, and backup options.

## I am experiencing some sluggish behavior in ENERCALC SEL. What can I do?

The first recommendation would be to use the following link to update to the latest available build: <https://install.enercalc.com/ECSEL20_SETUP.EXE>. Then perform a full restart and see how things behave.

If it continues to feel sluggish, use the following set of questions to guide you through some other common things to check:

1. Are you storing your Project Files on your local hard drive, or on a network drive?
2. If you’re storing them on a network drive, how does the performance change if you save them locally?
3. Are you currently using Microsoft Security Essentials? It has documented conflicts with the underlying programming language used to program ENERCALC SEL.
4. Are you aware that you can deselect the option to automatically produce backup files? Deselecting this option may improve performance.
5. Are you aware that you can deselect the option to automatically create and save calculation reports? Deselecting this option may improve performance.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.enercalc.com/sel-faq/using-the-software/general-operation/sluggish-behavior-in-structura.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
