[Galaxy S I9000 General] forgetmyname:
Test with K9 and default Android Email app on i9000

Did a test on my i9000. Stock 2.1 no lag fix. Bought SIM-Free so only has Samsung's tweaks and no mobile operator branding.

I9000XXJM1

ECLAIR.XWJM2

TEST A. Default Email application

1. Used Email app (default one that comes with Android):

Added two Gmail accounts / IMAP, SMTP, SSL.

No unacceptable lag other than that encounted without the usual lag-fix.

2. Added 1 non-Gmail account / IMAP/ SMTP-AUTH, TLS

System became nearly inoperative. Swiping between home screens took 2 seconds. Using most apps, caused the screen to remain black for between 2 and 30 seconds. In one case using Xscope (browser, which was now impossible to use - unresponsive and 3 mins to draw a page) caused the screen to remain black for approx 3 mins. Contact, Messenger and Phone apps took a max of 2 seconds to open, but always opened. Outbound call quality degraded to the point the called party complained. I did not notice an app crash.

TEST B. K9 Mail application

1. Used K9-Mail app :

Added two Gmail accounts / IMAP, SMTP, SSL.

No unacceptable lag other than that encounted without the usual lag-fix.

2. Added 1 non-Gmail account / IMAP/ SMTP-AUTH, TLS

System became nearly inoperative. Swiping between home screens took 2 seconds. Using most apps, caused the screen to remain black for between 2 and 30 seconds. In one case using Xscope (browser, which was now impossible to use - unresponsive and 3 mins to draw a page) caused the screen to remain black for approx 3 mins. Contact, Messenger and Phone apps took a few seconds to open. Outbound call quality degraded to the point the called party complained. I did not notice an app crash. System load hit 39, which is very overloaded for a 1 CPU device. Often it was between 10 and 20.

I suspect the I/O but I did not see iostat in busybox; the stdout from top was badly formatted on the SGS display so I could not read the I/O column.

Notes:

i. Test B Result 2 is almost a copy and past of Test A Result 2. This is because the results were pretty much the same.

ii. System load (vmstat and top) I did not check system load with Test A. I only did this when I used K9-Mail.

iii. System was rebooted each time after an IMAP account was configured.

iv. I have since removed the non-Gmail IMAP accounts. It was hell. I almost beat the SGS into the wall.

v. Important: the non-Gmail IMAP account has the following in the mailbox:

Inbox 658 messages totalling 68.4Mb.

vi. K9-Mail configured to fetch full headers and messages <2kB hourly, and only the fetch the Inbox.

vii. NON-Gmail IMAP server capacities:

* OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1 STARTTLS AUTH=PLAIN] Dovecot ready.

No problem here - Google use Dovecot.

viii. A factory reset was done between the two tests. (Settings -> Privacy -> Factory data reset)

viiii. GMAIL IMAP accounts contained approx 20 Emails each in the Inbox. I await more SPAM for testing purposes.

UPDATE.

I had 1,000 Emails sent to me on Gmail. Then reran Test A Part 1, and had the Email app load 114 of these. The SGS stated to lag. I opened one of the messages (containing only 1 line of ASCII email), and the Email partially opened the Email, splutted, stopped, hung, screen went black. Eventually, I closed the app down. Even the Active Applications widget (and the programme it lauches) is slow (and red).

I went onto Gmail and deleted the 1,000 Emails, and synced the Email app with Gmail IMAP server. Messages read 0, and the SGS was back to normal speed without lag-fix.

I soubt very much that any one is using a normal Email account with the SGS Email app. I suspect most are using Gmail with the Gmail application. I cannot comment on the lag fix (I await CyanogenMod for mine), but the SGS cannot be used with a non-Gmail account without a lag fix : useless for me since I only use Gmail for the Market ; Like many people, work provides the Email account. Clearly, Samsung test team did not test their wonderful RFS with normally sized IMAP accounts. Nice one, Samsung. 10 out of 10 for cocking it up.

As for GPS its something like thsi:

- Where are the sats?

Oh there they are.

Please don't move for 30 seconds.

Found some!

Oh feck, you've moved.

Now where are those pesky sats?

What was I doing? Oh sats!
