I want to display around 40k markers on the map. I tried like this but maximum is 10 (i read in documentation this is some sort of a limitation).

Here is my code: 
<apex:page standardController="Account" recordSetVar="accounts" >

  <apex:map width="1200px" height="1000px" mapType="roadmap"
    center="42.23  42.23">
        <apex:repeat value="{! accounts }" var="acc">
        <apex:mapMarker title="{! acc.Name }" position="{!acc.BillingLatitude}, {!acc.BillingLongitude},{!acc.BillingCity}, {!acc.Billing_Zip_Postal_Code__c}" />
        </apex:repeat>
  </apex:map>
  </apex:page>

Is there any posibility to do that ? 

Hi Experts

We have serveral partners each with thier own login URL, which we would like to bring into a single shared login screen.

e.g.
myinstance.force.com/partner1/login
​myinstance.force.com/partner2/login

Is there a way to have one single login screen and it login to the correct partner depending on thier username/profile?

e.g.
myinstance.force.com/login

Any help would be apreciated.
