Serious Lag When Using Software - Especially Terminal Computer

V5 Issue

Could be a lot of things. I’ve had the same problem happen to me. Here’s the troubleshooting that I did.

  1. Your database size or your HDD/SSD may be approaching it’s capacity.

  • If your DB size is getting full (which is naturally hard to do), you probably added new Rules and Actions that clutter up your DB or take up too much CPU/RAM (I followed this tutorial [.com/t/creating-ticket-logs-to-improve-security/7432] and every action I did on the POS, it would log it into the DB and if you do have this tutorial, set it to work in background.)

  • SSDs are good, but they can fail very easily. Constant read/writes can wear them down faster than it would an HDD. Spend a little more money on a commercial server-grade SSD that won’t wear down as quickly.

  1. Internet connection

  • If your terminals are on wifi, it’s time to move to ethernet cables. (Things that can cause wifi interference: microwave ovens, wireless keyboards, wireless mice, wireless barcode scanners, etc.)

  • DON’T use flat ethernet cables. They have a higher gauge than the round cables, which are less prone to interference. Flat cables are usually 30 AWG, while the round ones are 24 AWG.

  • If you’re already using ethernet cables, then use a ethernet cable tester from Amazon and see if there is any damage to them.

  • It’s winter and you have the heat up in the room. Your internet router may be too close a heat source or something and it maybe throttling itself.

  1. Server Computer

  • Maybe there’s a lot of dust in the computer, which causes it to overheat, which causes it to throttle itself.

  • Maybe one of your RAM sticks is dead, and you’re on only 1 GB of RAM.

  • Maybe your Power Supply Unit in your server computer is dying and your motherboard isn’t able to pull the necessary amount of voltage from the PSU.

  • Unnecessary programs may be running on the server computer.
