I need to be able to make 100 transactions from 1 address to 1 other address (so no addresses ever mixed in any transaction)
So A -> B1, A -> B2, ... but not A -> B1, B2, ... (it's complicated to explain why but it's necessary)
So I need a lot of transactions with each a small fee too.
How can I process something like that?

Not sure I understand you correctly but you'll probably need to send them one by one. You may be able to get away without including a fee but depends how much the amounts are. The money will still be able to be traced back to you though.

Yes, is there a fast way to start a lot of transactions?

Might look in services.  I know one person (no longer doing it) ran a macro to send shares payment each week.  I think he used a macro, and might have paid someone to make it if i remember right.

Is it sending to same address each time?

yes, sending to the same 100 addresses all the time
is he on bitcointalk?

You can include multiple outputs and save fees.
But you need to have PC wallet, because online wallets don't allow such stuff

no, i do need seperate transactions, and with blockchain.info api sending from or to more addresses is possible
but i need a way to make a lot of transactions, probably a small program or something

Automatically? You can have many hundred outputs using blockchain.info but you will need to input data manually or program a bot to enter the values in the appropriate fields.

can i find such a bot somewhere? i cant program at all
I really really need it...

someone told me that after 100 transactions start trouble with sync. Is it true?

No.  It is not true.

If you are using the Bitcoin Core wallet, then you should create a new backup of the wallet before you have performed 100 transactions since your previous backup.  This is not because of any "trouble with sync". It is because the wallet pre-generates the next 100 private keys that it will use and it uses a new private key with each transaction sent.

That was about MultiBit..
So if i'm using  MultiBit - i should to do something now before 100 tx or i should to wait when i reach 100 and then do something? But in I write "something" because in MultiBit i can not find backup option - i just copy all from %appdata% MultiBit ..

I haven't used Multibit myself, but AFAIK, Multibit doesn't use a keypool at all and it doesn't use a new change address (it simply uses one of the input address to receive the change).

You have to build and broadcast the transaction with the input(s) and the outputs.

Look into using https://www.asmoney.com/ they might have something that will support this. They do have support for multiple payments and multiple currencies.

Not AssMoney  ;D ;D ;D

You can send your bitcoins to many address to save fees.
This is something many faucets do to save transaction fees to give out more to everyone.

Why would he need that?

I think he only needs to create a raw transaction with createrawtransaction [{"txid":txid,"vout":n},...] {address:amount,...}
Of course he could create a little scritp to do that if it is a common task form him.
