Filezilla Slow

[Andree Vandestreek]

When transferring files using FileZilla, it's important to understand the factors that can affect transfer speeds. Transfer speeds can vary based on a variety of factors, including your internet connection, the server's bandwidth and hard drive speed, and the transfer settings you use in FileZilla.

Your internet connection is one of the most important factors that can impact transfer speeds. If you have a slow or unstable internet connection, you may experience slower transfer speeds. To optimize your transfer speeds, make sure you have a stable and fast internet connection.

Reboot your router and modem: Sometimes, your router and modem can experience issues that slow down your internet connection. Try turning off your router and modem for a few seconds and then turning them back on. This can help reset the connection and improve transfer speeds.

Check your internet speed: You can use online speed testing tools to check your internet speed. If your internet speed is much slower than expected, contact your internet service provider (ISP) to troubleshoot any issues with your connection.

Use a wired connection: Wireless connections can be slower and less stable than wired connections. If possible, try connecting your device to your router or modem using an Ethernet cable to improve transfer speeds.

The transfer settings you use in FileZilla can also impact transfer speeds. For example, you can try increasing the number of simultaneous transfers or adjusting the buffer size to optimize transfer speeds.

To increase the number of simultaneous transfers, adjust the value in the "Maximum simultaneous transfers" field. You can increase this value to improve transfer speeds, but be mindful of your computer's performance.

When you transfer files, your computer may use RAM as a temporary storage location to speed up the process. However, if you're transferring large or multiple files at once, your RAM might become full and start slowing down the transfer speed. It's like trying to fill a small cup with too much liquid - the cup will overflow, making a mess and slowing down the pouring process.

The more space you use beyond a certain point, the slower it gets because of non-contiguous files. When you transfer files, your computer needs to find available space on the destination drive to write the files. If the destination drive has a lot of non-contiguous free space, meaning that the available space is scattered throughout the drive rather than being in one contiguous block, the transfer speed can slow down as your computer searches for available space. It's like trying to fill a large bowl with small pieces of fruit - you have to search for each piece and fit them in one by one, which takes longer than pouring a single type of fruit into the bowl.

A fragmented file system occurs when files are broken up into smaller pieces and scattered across different parts of the hard drive. This can happen over time as files are created, edited, and deleted. When you're transferring files to a fragmented file system, the transfer speed can slow down as your computer has to read and write from different parts of the hard drive. It's like trying to make a smoothie with a bunch of frozen fruit chunks that are stuck together - you have to break them up and blend them separately, which takes longer than blending a single, unfrozen piece of fruit.

Your computer's cache is a temporary storage location that helps speed up data access by storing frequently used files and data. When you're transferring large files to a spinning hard drive, the cache can fill up quickly, and your computer may struggle to keep up with writing raw data to the disk, leading to slower transfer speeds. It's like trying to eat too many appetizers before the main course - you may fill up on the appetizers and not have enough room in your stomach for the main course, which slows down the eating process.

If you're experiencing slow transfer speeds on the server side, you can try decreasing the number of active torrent downloads on your seedbox, limiting the number of active Plex streams, or log out of Remote Desktop to improve transfer speeds.

If you're experiencing slow transfer speeds on the client side, make sure you have a stable and fast internet connection. You can also adjust the transfer settings in FileZilla to optimize the transfer speed. Additionally, you can try closing any other programs or applications that may be using bandwidth and slowing down your transfer speeds.

A: MiB/s and Mbps are both ways to measure how fast data is being transferred. When you download a game, you want to know how much of the game is being downloaded every second and how fast it's being downloaded.

Think of it like this - imagine you're filling up a swimming pool with water. You want to know how much water is going into the pool every second (like MiB/s) and how fast the water is going into the pool (like Mbps).

MiB/s measures how much data is being transferred every second. It's like measuring how much water is going into the pool every second. So, if you're downloading a game and it's transferring at 1 MiB/s, it means that 1,048,576 bytes of the game are being downloaded every second.

Mbps, on the other hand, measures how fast the data is being transferred. It's like measuring how fast the water is going into the pool. So, if you're downloading a game and it's transferring at 1 Mbps, it means that 1,000,000 bits of the game are being downloaded every second.

It's important to understand both measurements when you're downloading a game or transferring any type of data. MiB/s tells you how much data is being transferred at once, while Mbps tells you how fast the data is being transferred.

By understanding both measurements, you can get a clear idea of how your downloads and transfers are going, just like how you can get a clear idea of how much water is going into the pool and how fast it's going in.

A: There are several ways to optimize your transfer speeds in FileZilla. For example, you can try adjusting the transfer settings, increasing the number of simultaneous transfers, or adjusting the buffer size. Additionally, you can try using a wired internet connection rather than a wireless connection, as wired connections tend to be more stable and faster.

A: Slow transfer speeds can be caused by a variety of factors, such as server bandwidth limitations, network congestion, or issues with your computer's hardware or software. It's important to identify the root cause of the issue before attempting to troubleshoot it.

A: Yes, antivirus software can sometimes slow down transfer speeds by scanning files as they are being transferred. You can try temporarily disabling your antivirus software to see if it improves transfer speeds.

Close other programs and processes running on your computer to free up RAM. Think of it like cooking in a small kitchen - if you have too many pots and pans on the stove, it can slow down the cooking process.

Defragment your hard drive to ensure that files are stored in contiguous blocks. Think of it like organizing your pantry - if everything is in its proper place, it's easier to find what you need quickly.

Use a disk cleanup tool to remove unnecessary files and free up space on your hard drive. Think of it like cleaning out your refrigerator - if you remove expired or unused items, you'll have more space for the things you actually need.

Consider upgrading to a solid-state drive (SSD), which can provide faster transfer speeds compared to spinning hard drives. Think of it like upgrading to a new set of knives - a sharper knife will make cutting and preparing ingredients faster and more efficient.

Transfer files in smaller batches to avoid overloading your computer's cache. Think of it like baking a cake - if you add too much batter to the pan, it can overflow and make a mess. Similarly, transferring too many files at once can overload your computer's cache and slow down the transfer speed.

I have also other servers with same OS but different kernels, but the problem is the same there, transfering files are limited to 1.5MB/s (and haven't been before - when I installed them and transferred what I needed on them).

All transfers are now slow at 1.5MB/s even between the servers and that's pretty annoying, because I can transfer 10 different files and they would all transfer at 1.5MB/s, but if it is only one file, the speed wouldn't increase.

When using the FileZilla FTP client with the default settings, in some cases you may experience slow speed when uploading or downloading files. This guide will help you to optimize the settings of your FileZilla FTP client to get the best possible upload and download speed.

If you are uploading (downloading) many files in a single FTP session, the easiest way to maximize your FTP speed is to increase the number of concurrent downloads. This allows you to bypass FTP server restrictions that limit the maximum file upload speed for a session.

Restart the FTP session. This way you will allow the FTP client to download or upload simultaneously 10 files in parallel sessions (threads). It is not recommended to set a value higher than 10. This is because multiple simultaneous sessions from your FileZilla client can overload the remote FTP server.

Active FTP transfer mode provides faster speeds than Passive. However, active mode requires a public (dedicated) IP address on your computer, which is rare. You can only use passive FTP transfer mode if your computer is behind a NAT or proxy server.

During installation, the FileZilla client automatically adds firewall rules to accept FTP traffic. These rules allow inbound/outbound traffic associated with the FileZilla app. If one of the FileZilla ports is closed in your firewall, it may slow down your FTP speed. Open the Windows Defender Firewall inbound rule list and make sure that the FileZilla FTP Client rules are enabled.

Connect to the specified FTP server and try uploading and then downloading a large file. Measure the speed of the connection and compare it with the download speed of your FTP server. The screenshot shows that the average speed of uploading files via FTP to a free service is about 3MiB/s.
