Upper limit on Operations per Request

[Ian]

While doing some performance testing on our application against the
sandbox. I've been hitting this error:

<detail>
        <ApiExceptionFault xmlns="https://adwords.google.com/api/adwords/cm/
v201109">
                <message>RateExceededError &lt;rateName=Operations,
rateKey=new_request, rateScope=ACCOUNT, retryAfterSeconds=30&gt;</
message>
                
<ApplicationException.Type>ApiException</ApplicationException.Type>
                <errors xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";

                        <trigger></trigger>
                        
<errorString>RateExceededError.RATE_EXCEEDED</errorString>
                        <ApiError.Type>RateExceededError</ApiError.Type>
                        <reason>RATE_EXCEEDED</reason>
                        <rateName>Operations</rateName>
                        <rateScope>ACCOUNT</rateScope>
                        <retryAfterSeconds>30</retryAfterSeconds>
                </errors>
        </ApiExceptionFault>
</detail>

According to this page: 
http://code.google.com/apis/adwords/docs/appendix/limits.html
the limit per request is 2000, has this changed recently? if so what
is the new limit/recommendation?
