RE: slow response time

RE: authentication error
Nope, nothing out of the ordinary. I tested this about 5 times last night and EVERY time the show processlist was 100 or above, it hung. The ONLY variable I can find with a setting of 100 is that delayed_insert_limit.

RE: Server tuning
Victor, Thanks for all your help with the authentication issue. I still have it, but at least I know what to look for. My server is running RH9 with 3 gigs ram, PIII. I have about 150 users at any given time and they're all coming via IMAP or HTTPD. They all authenticate against MySQL but the mail is not stored there, it's in virtual domain files. My /etc/my.cnf Set-variabe = max_connections=1000 Key_buffer_size=512M Sort_buffer=20M Join_buffer=1M Record_buffer=1M Max_allowed_packet=2M Table_cache=1024 Innodb_buffer_pool_size=256M Are these variables ok? Reading my MySql manual, these were the best I could come up with.

I took a look at the variables at global my.cnf and wondered what would be the best values for things like key_buffer, read_buffer_size and table_cache. I searched the manual, but it does not go deep in this subject, or I was not capable of finding the right place. What I want to know is how can I calculate how much memory I should give to key_buffer before I start to give away too much memory. That's because I got only 1GB of RAM and I have about 34k domains in my database, averaging from 8 to 15 accounts each. In a normal situation, there are ~400 simultaneous clients. I was wanting to know how can I estimate the memory usage for this scenario, if exists some kind of formula to answer this, like: clients * total size of key fields used in query or if this is some thing that is clear in the manual (if so, my apologies, but I could not find).

RE: authentication error
Is there anything I should set in my startup options to accommodate this? -Original Message- From: Victor Pendleton [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 29, 2004 1:54 PM To: Chip Bell; Victor Pendleton; '[EMAIL PROTECTED] ' Subject: RE: authentication error The values in the `State` and `Command` fields of the queries are what you should be looking at. For example if you have a select statement that is running over an acceptable threshold you should look into that. If you have a query that is taking a `long` time to create a temp table , you should look at that one. You just need to identify what is acceptable and normal behaviour and correct where possible. -Original Message- From: Chip Bell To: Victor Pendleton; [EMAIL PROTECTED] Sent: 6/29/04 12:43 PM Subject: RE: authentication error Ok, we might be on to something.

Please help..
Hello, I have a Red Hat 9 server which runs a qmail/toaster software package. It allows webmail to authenticate against a mysql db and stores mail there too. K, the issue.. Every once in a while, the web client just SITS at authentication. The client just sits there forever. The login can take up to 85 seconds. Once you are logged into webmail however, it's very very fast. Another note, when myself and my admin are waiting to login, it seems we both finally get through at the same exact time. I don't know where to look to see what's causing this but everything points to my database. A restart of the server will fix the issue...but that's just a workaround. Hardware: P3 1ghz, 3gigs ram, Ultra3 Scsi (Raid 5) I appreciate ANY help you can give. This is a production box and it's causing problems! /etc/my.cnf set-variable = max_connections=1000 set-variable = key_buffer_size=1024M set-variable = sort_buffer=20M #set-variable = read_buffer_size=2M set-variable = join_buffer=1M set-variable = record_buffer=1M set-variable = max_allowed_packet=2M set-variable = table_cache=1024 set-variable = innodb_buffer_pool_size=256M #set-variable = query_cache_limit=1048576 #set-variable = query_cache_size=0 Mysql 3.23.58-1.9
