Modpack installation issue

[blackrave]

Hi guys, first thread here

So whenever I pick custom modpack launcher

1. Downloads files from Minecraft.net- this goes fast and without issues

2. Downloads archived modpack itself- kinda slow, but I understand that it's bandwidth issue

3. Sets up mod- and it is SLOOOOOOOOOOOW as hell (and lags my machine)

For example

I tried to get Aether Super+ Experimental pack

http://www.technicpack.net/modpack/details/aether-super-pack.56541

steps 1&2 went ok, 3rd step lasted for more than 3h and I was forced to stop it (because I have other things to do)

Other modpacks behave in similar manner.

Is this normal?

If yes, then why? And can I somehow instal modpacks manually?

If no, then why this is happening? And how can I fix this?

TIA

Try increasing your allocated RAM. That might help.

Try increasing your allocated RAM. That might help.

Increased as much as launcher allowed (only 1Gb for some reasons)

According to status bar launcher does things, but unpacking drags insanely slow

Are you running 64-bit or 32-bit OS? If you're running 32-bit, you are limited to the amount of RAM you can allocate, assuming you've got a non-integrated graphics card, the system would only have about 3GB left to use (and that's assuming you've maxed out your RAM at 4GB as well).

It sounds like you have 32-bit Java, if it's only letting you allocate that much RAM. However, unpacking mod packs should not really be using much in the way of system resources, so I don't know what's going on from that end.

Is there any way to manually instal a modpack then?
