What may cause this?

Here some results,

As admin, my profile page (when looking at others profiles pop_profile.asp) is created like 0.8 seconds, as user 32.85 seconds... But there should not be that much difference between admin & user, right? I mean where I can try to find solution in codes?

What may cause this?

Mods I have installed:
- Anti-spam mod (cant recall exact name)
- Avatar mod
- Poll mod
- Active Users

NOTE: I have tried it several times and got it tried to some of my users.

TXT Version of POP_PROFILE.ASP

TXT Version of INC_PROFILE.ASP

Very weird. That's not a common issue at all. Maybe post a link to a text version of your pop_profile.asp and inc_profile.asp files.

You might want to try to disable the Recent Topics feature (Admin Options -> Member Details Configuration) and see if it makes any difference.<

This won't help you but it happened here at Snitz once - http://forum.snitz.com/forum/topic.asp?ARCHIVE=true&TOPIC_ID=57286&whichpage=1

No cause found. It was fixed by moving to a new server.<

It is almost very same problem. HuWR was getting fast results as admin, but users dont, hence I dont have chance to change my host since it is co-location computer. Just wondering if it is from MSSQL settings should be different or what.

SiSL,

In your pop_profile.asp, around line# 399, here now you have,


                                        strsql = "SELECT F.FORUM_ID"
					strSql = strSql & ", T.TOPIC_ID"
					strSql = strSql & ", T.T_SUBJECT"
					strSql = strSql & ", T.T_STATUS"
					strSql = strSql & ", T.T_LAST_POST"
					strSql = strSql & ", T.T_REPLIES "
					strSql = strSql & " FROM ((" & strTablePrefix & "FORUM F LEFT JOIN " & strTablePrefix & "TOPICS T"
					strSql = strSql & " ON F.FORUM_ID = T.FORUM_ID) LEFT JOIN " & strTablePrefix & "REPLY R"
					strSql = strSql & " ON T.TOPIC_ID = R.TOPIC_ID) "
					strSql = strSql & " WHERE (T_DATE > '" & strStartDate & "') "
					strSql = strSql & " AND (T.T_AUTHOR = " & ppMember_ID
					strSql = strSql & " OR R.R_AUTHOR = " & ppMember_ID & ")"
					strSql = strSql & " AND (T_STATUS < 2 OR R_STATUS < 2)"
					strSql = strSql & " AND F.F_TYPE = 0"
					strSql = strSql & " ORDER BY T.T_LAST_POST DESC, T.TOPIC_ID DESC"

replace it by


	                                strsql = "SELECT F.FORUM_ID"
					strSql = strSql & ", T.TOPIC_ID"
					strSql = strSql & ", T.T_SUBJECT"
					strSql = strSql & ", T.T_STATUS"
					strSql = strSql & ", T.T_LAST_POST"
					strSql = strSql & ", T.T_REPLIES "
					strSql = strSql & " FROM (" & strTablePrefix & "FORUM F INNER JOIN " & strTablePrefix & "TOPICS T"
					strSql = strSql & " ON F.FORUM_ID = T.FORUM_ID)"
					strSql = strSql & " WHERE (T_DATE > '" & strStartDate & "') "
					strSql = strSql & " AND (T.T_AUTHOR = " & ppMember_ID & ")"
					strSql = strSql & " AND (T_STATUS < 2)"
					strSql = strSql & " AND (T_REPLIES < 1) AND F.F_TYPE = 0"
					strSql = strSql & " UNION"
					strsql = strsql & " SELECT F.FORUM_ID"
					strSql = strSql & ", T.TOPIC_ID"
					strSql = strSql & ", T.T_SUBJECT"
					strSql = strSql & ", T.T_STATUS"
					strSql = strSql & ", T.T_LAST_POST"
					strSql = strSql & ", T.T_REPLIES "
					strSql = strSql & " FROM ((" & strTablePrefix & "FORUM F INNER JOIN " & strTablePrefix & "TOPICS T"
					strSql = strSql & " ON F.FORUM_ID = T.FORUM_ID) INNER JOIN " & strTablePrefix & "REPLY R"
					strSql = strSql & " ON T.TOPIC_ID = R.TOPIC_ID) "
					strSql = strSql & " WHERE (T_DATE > '" & strStartDate & "') "
					strSql = strSql & " AND (R.R_AUTHOR = " & ppMember_ID & ")"
					strSql = strSql & " AND (T_STATUS < 2 OR R_STATUS < 2)"
					strSql = strSql & " AND F.F_TYPE = 0"
					strSql = strSql & " ORDER BY T.T_LAST_POST DESC, T.TOPIC_ID DESC"

Let me know if it improves on your problem.

P.S.:This code is good only for Access or SQL Server. MySQL versions that support UNIONS (4.0+) should also be ok, BUT NO TESTING WAS DONE.<

Can you compare both versions of the file (with and without the change) regarding the recent posts that appear for each user? I think they should be, but want to be sure...<

The difference in performance quite surely results from the fact that each topic must be evaluated against users permissions, to ensure that the user viewing the profile has access to the topics.

Using getrows instead of the navigating the recordset could also help improving the performance.<

I did some testing my avarage non-admin user see ~23-24 seconds..

With latest code, that didnt change actually. Above user & pass active for each code changes.

Is it from setup variables or something I had to do with settings of MSSQL to increase performance?

I don't know MySQL that well. Don't use this until I get the chance to test it with it.<
