Help Me Optimize A Daily Events Query

We keep a database of events that are classified by severity. I've got a good, efficient query that gives me the grand total for these events. And I have a bad slow query that breaks down the information into daily totals.

My fast query will count the totals for 3213586 events in 4 seconds. The slow daily query takes about 60 seconds for each day.

Please help optimize my slow query!

------- The database view eventView that's used by my queries:
SELECT DATEADD([second], [time] + 60 * offset, '01/01/70') AS timeStr, msec, host, process, dbName, ptName AS point, description, rtuName AS rtu, groupName, message, type, sevInt, [time]
FROM dbo.summary

------- Fast totals query:

select
(select count(*)
from [event].[dbo].[eventView]) as Events,
(select count(*)
from [event].[dbo].[eventView]
where type = 'alarm' and sevInt = 1)as Low,
(select count(*)
from [event].[dbo].[eventView]
where type = 'alarm' and sevInt = 2)as Medium,
(select count(*)
from [event].[dbo].[eventView]
where type = 'alarm' and sevInt = 3) as High,
(select count(*)
from [event].[dbo].[eventView]
where type = 'alarm' and sevInt = 4) as Low1,
(select count(*)
from [event].[dbo].[eventView]
where type = 'alarm' and sevInt = 6) as Medium1,
(select count(*)
from [event].[dbo].[eventView]
where type = 'alarm' and sevInt = 8) as High1,
(select count(*)
from [event].[dbo].[eventView]
where type = 'alarm' and sevInt = 9) as High2

------- Slow daily query:
