How to check how much memory is being used for a software and how to increase memory for it?

cw flag

Specifically, I'm using Ubuntu 22.04 and since the Rstudio software gets laggy sometimes, I want to check how much memory is being used for Rstudio and how to grant more memory for it.

How should I do this?

Add swap space. Use `free` to see RAM & swap. Read `man mkswap swapon fallocate fstab`. Don't create a swapfile with `dd`.

Could you explain in details how to do that?

No. Not knowing your system, not knowing your environment, not knowing what else is running, not wanting to instantiate a "support" relationship with a user desiring a "flip Switch B" type answer, I won't. Read The Fine Manuals, RTFM.

Ubuntu has a system monitor application that you can use to monitor memory usage

You don't "grant more memory" to specific applications. The kernel will automatically manage memory for you, and it's quite clever about doing so. Do not try to defeat the kernel

If your system begins to lag, that typically means that your system has exhausted your available memory (RAM) and is swapping pages to storage (disk)...which is much slower, hence the lag.

  • Use the shell command free -h or your GUI System Monitor application to view a snapshot of your current memory availability.

  • Sometimes you can free some additional memory by closing unnecessary applications.

  • Sometimes you need more hardware memory.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
