Regardless of the number of bars, is the download speed similar or very different under the two versions? (I ask because there was some talk earlier about the number of bars becoming a more accurate assessment -- I don't know if this has been implemented). Try this (or related sites) to get a reading: https://speakeasy.net/speedtest/ Note that there is, quite naturally, tremendous variability, so you may have to do it a large number of times to get a fair reading under each distribution. I have not myself noticed a difference. HTH somewhat. Ranjan -- Important Notice: This mailbox is ignored: e-mails are set to be deleted on receipt.
