Torrents slowing pc down

[venomx]

when I download large files it lags my pc
Why is this ?

[RobertX]

Torrent downloading takes a lot of system resources.

When I download stuff while encoding my shows, either one (or both) of the elements in the entire equation slows down.

First you should check the usage in your system running resource monitor to determine the source of slow downs.

Maybe you got too small amount of RAM as bigger files probably use more cache so you could go into settings of your torrent client and put a limit on the cache.
Could be vice-versa as well, if you got too small cache the disk usage will be higher those increasing times to load programs, etc.

You can also limit the process to use only some of the cores of your CPU, just right click it in the process list in your task manager(detailed view) and set affinity, also you can change the priority while you there.
By default it will be assigned to all cores and normal priority.

Trying different torrent client is also a good idea, from my experience Vuze(Azureus) is more CPU intensive than BitTorrent(client).

*I assumed you're on M$ Windows, for linux it's very similar.

Its writing to disc that does it, all torrent clients will happily eat up all your bandwidth and all your available disc usage so it's up to you to set your client for your system, if you set the download speed lower then the client wont be hashing as fast and writing to disc as fast and you won't get any lag.

Ideally if you have two separate drives use one for you're downloads.

Writing to disc with NTFS or other windows file systems is slowing it down.

Windows file systems are very inefficient and will wear out your drives much faster with constant read/writes.

It has a lot to do with the fact that they are poorly designed.

Thanks guys

Torrenting consists of getting a chunk of data and writing it to disk if you're downloading, the other way around if uploading.
10-30MB/s is usual on IDE, as 2MB chunks on torrented material. Seek times aside, your hard drive can deal with a bunch of active torrents.
If not, something is wrong, but more detail is needed.

- Use a temporary drive for your downloads, preferably a SSD, but a USB stick / SD card will help - No fragmentation and seek time problems.
- Keep your torrent in the temp drive until you finished seeding it at least 1.0 (if you care to), don't set your client to move it to the HDD just after downloading.
- Configure a huge RAM cache for your data drive or move your active uploads to a temporary SSD place, like the downloads.
- There're automated cache management utilities, but I never needed to go that far; current systems are balanced out of the box, but your case is yours only.
- Consider using hybrid drives (like those 2TB HDD / 8GB SSD combos) or a NAS, or even professional Back-uped-RAM drives if you're a crazy rich torrentor.

- If none is possible, try partitioning and/or at least defragmenting your hard drive. Big files scattered all around are bad; partitions limit this into smaller areas.

Increasing performance beyond that requires system tunning or hardware replacement; either that or there's something wrong in your system.

Sorry, late by a couple minutes!

Or use ext4 or another decent file system and a decent OS like linux and a decent PC from the last decade. No need for ram cache or ssd.

Only windows file systems need to be defragged. Because they are garbage.
