Forums mIRC Help Painfully slow DCC transfers..

I have all my ports opened in my router, DCC works just fine.. it's just extremely slow. My typical upload speed is around 250kB/sec.. I can't seem to DCC send files to people at more than 20kB/sec, no matter where they live and no matter how fast their connections are.

I can send 1 file to someone at a maximum of about 15k/sec, but if I send 2 files to that person, both files go at 15k/sec each. It makes no sense unless there's a setting somewhere I'm missing.

Someone suggested I go to Select Server > DCC > Fserve and change the max cps to 0 instead of the default 8192, and I did, and it didn't help. I also have /fsend on.

Any ideas why this is happening?

If it makes any difference I have Vista Business.

DCC has never been a fast method of transferring files. It's mainly meant for things like small pictures or text files, not mp3s or movies. In fact, this board has a policy against helping people with filesharing, not that we have anything against filesharing, but rather, the fact that we don't support illegal filesharing, which is a majority of what filesharing is.

The fact that you are using Vista may be having an effect, as there have been a lot of issues between Vista and mIRC.

Perform a search for Vista and you'll be able to see some of the topics.

You've already done everything that I'm aware of to be tried, while keeping with the DCC protocol.

Sorry I wasn't able to be of much (if any) help.

What kind of speeds were acheived before you got Vista?

As a note, some ISPs limit DCC send speeds. You can send faster on other protocols, but the DCC speed is limited due to it being used by so many people to send illegal files. Beyond this, ISPs can even block sends and/or downloads of specific file types if they choose to (such as .mp3), though that's most common in universities and not with your normal ISP.

Edit: Btw, you probably know what you are meaning by your speeds, but just to make sure... Is 250k your typical send speed to someone using another program, or is that what your ISP tells you that your upload speed is? 250kbit upload speed (probably 256kbit) would really be a speed of around 25-30kB/s actual speed.

32k/s actually

Yeah, yeah. I didn't calculate it out and it's been a long time since I've had that slow of an upload. Besides, due to connections between you and the receiver, you're usually not hitting the maximum anyhow. kbit/8 is maximum and kbit/10 is what's considered to be the more likely speed after taking into account connection/speed issues between you and the sender. Granted, I did tend to break 30kB/s when I had 256kbit upload on DSL years ago.

Now, if I had FIOS.... oooh! 2mbit upload/15-20mbit download at the same price as my 768kbit/8mbit cable.
