Cache Redis do Azure - Vários erros TimeoutException: Tempo limite executando GET {key}

Implantamos nosso aplicativo no Azure. Ele está usando o Cache Redis do Azure e estamos enfrentando alguns tempos limite. Nomeadamente:

[TimeoutException: Timeout performing GET textobjectDetails__23290_TextObject, inst: 1, mgr: Inactive, queue: 5, qu=0, qs=5, qc=0, wr=0/0, in=56864/0]

Consulte nossas configurações de tempo limite:

retryTimeoutInMilliseconds = "5000" 
connectionTimeoutInMilliseconds = "5000" 
operationTimeoutInMilliseconds = "1000"

Como abordar esses tempos limite? Aumentar operationTimeoutInMilliseconds faria o truque? Também li que a compressão g-zip é útil para diminuir o tempo necessário para ler os dados do Redis.

Todos os pacotes de pepitas relacionados ao Redis estão em suas versões mais recentes. Estamos usando a versão C1 do Azure Redis Cache (aumentaria para C2 ajuda?).
